Seeking a US source for sodium nitrite that ships residential

Sir_Nobel - 15-12-2025 at 17:45

I know with the on-going trend lately of others misusing NaNO₂, and as such as become more difficult to obtain sadly.

Most places won't ship to residential addresses and understandably so with what's been happening over the years.

I'm fine in terms of other reagents and lab ware.

I've found only one source overseas through the wiki however rather not have to deal with duties and fees. As well the possibility of a loss package.

Any help would be appreciated. Seeking 250g if possible. Preferably ACS grade

Welcome to the forum!

Nitrite is indispensable for Sandmeyer reactions, and I agree: it's a shame people had to abuse it. I believe it's available from Chem-Impex (an IL-based company), though I haven't heard if they do residential shipping (please let me know if they do). An individual also showed that it can be made by the amateur, with some difficulty. The link to the thread is referenced below.

If you go the home prep route you are more likely to get a nitrite/nitrate mixture. But the easiest route to high purity nitrite is either to precipitate silver nitrite and react that with the chloride of your desired nitrite salt, or use alcohol/water mixtures for separation. Sodium nitrite is almost 10 times more soluble in a 50% aqueous ethanol mix than sodium nitrate. You can at least concentrate the the nitrite up to 80-90% that way.

It is now illegal to ship to individuals in certain states in the usa. Resulting in most businesses refusing to ship to residential addresses. And there is a law to ban nitrite sales to individuals on the federal level in progress.

That's unfortunate. I was under the impression that the feds were moving toward DE-regulation, but I digress.

For the Sandmeyer reaction, I've seen a couple of alternatives. In this paper, nitrite is generated in situ by nitrate reduction with thiosulfate, which would mean a slower reaction time, but much more attainable to the amateur than nitrite synthesis. Additionally, it was reported in this thread, that uses a Sandmeyer-like reaction on glycine, using nitric and muriatic acids to produce chloroacetic acid with some reported success.

I could not send via U2U so here is the label

The thiosulfate sounds reasonable as nitrate to nitrite reduction is favorable in mild reducing conditions. Oxosulfur anions are the best route. Just gentle enough that you don’t get carbonate or free alkali but strong enough to give decent yield. The most satisfactory methods for making nitrite, according to Apoptosis on YouTube, is the careful thermal reduction of potassium or sodium nitrate with calcium sulfite. Also, absorbing mixed nitrogen oxides in KOH or Ba(OH)₂ would provide a means for easy separation

charley1957 - 17-12-2025 at 09:39

I just called Chem-Impex and was told they only ship to commercial addresses.

I think I explained why. Some places will sell potassium nitrite that isn't as regulated.

violet sin - 18-12-2025 at 08:36

So is this as an effort to stop people from taking matters into their own hands, or from people using it on others? Seems pretty messed up if there's enough people that sad/broken hearted to justify making laws against sale to individuals. At least with other chems the complaints were building blocks for illegal activity.

jackchem2001 - 19-12-2025 at 02:34

I have had success doing reactions with nitrite made by roasting potassium nitrate with calcium sulfite. The dry powders are mixed well and heated to 500-550 degrees (wall IR temperature) in a small 100mL RBF. Only 50mL of reaction mix can be processed at once or even heating becomes challenging. I will not use that RBF ever again due to the temperature used + calcium embrittlement possibility.

They've been the only source I've found even though they're not US based.

I haven't been able to find a US based company that sells to residential.

I'm only looking for 250g at the moment so not a bulk order either.

Have you had any issues with duties & import fees when dealing with Onxymet?

They also don't list the grade or any information either which has also had me hesitant.

I'd be looking at around $160 from onyxmet

That’s definitely too much.. I remember you could get 2Kg for $20 S&H on eBay a few years ago lol. I just bought 500g for about $20 a year ago from someone on these forums. Your best bet really is to look for a private seller or for a post on these forums with someone selling.

There’s also pro-cure’s 99% tech grade sodium nitrite meant for fish egg curing. It’s not listed on many websites, but if you call procure themselves you can probably buy some.

With enough digging and effort, you can definitely find a cheap source.

Onyxmet has KNO2 for 15 euros per 100 gram, which is a decent price.

Oldmanboomer50 - 22-12-2025 at 19:14

Anyone order from Synthetika in Poland? Shipping is high but the product price is about 9 bucks for 500g.

woelen - 23-12-2025 at 04:53

I have experience with Synthetikaeu.com, and actually got NaNO2 from them. But nitrite is not shipped to the USA, except to government-approved licensed organizations. Apparently, nitrite is quite heavily regulated in the USA, much more so than in the EU. Synthetika respects this kind of regulations. Some chemicals are not shipped to specific countries (there also are a few chemicals, which specifically are not shipped to the Netherlands and a few other EU-countries, e.g. P2NP).

For me its about $6 per 10 gram.

I dont how you're seeing 15 euros for 100 grams? it shows 5 euros per 10 grams

So that would be 30 grams at 15€

I believe that stopped being manufactured as its been sold everywhere

Theirs currently no regulation for it in the US as of yet. Chemical companies have just been quite strict in general where they will only ship to Schools, Labs, Govt, or Companies.

The problem is due to misuse of reagent by normal individuals for unfortunate reasons.

Wht you are looking at is NaNO2. The price I mentioned is for KNO2. But the latter can replace NaNO2 in most experiments.

Your correct and I apologize. I zoned out and just looked up the pricing for sodium nitrite and overlooked when you said KNO2 referring to potassium nitrite.

KNO2 is not much of an issue to procure in the states as much as sodium nitrite is. I do have some already so I wouldn't require more. I appreciate the information though

Forgive my ignorance but I'm not familiar with them and as a newcomer to the site; maybe they have history.

I checked the wiki but I see no information on their credibility and reliability.

I'd appreciate any prior to purchasing

A quick search is not giving me promising results

I believe many of us in this forum wanted to keep track of reliable and unreliable chemical sources, so thank you for letting us know that this website is risky.

P.S. I’ve also found an old SM post about this website: www.sciencemadness.org/talk/viewthread.php?tid=8270

Seems like their fraud started a long time ago

Unfortunately, it seems that way.

From what I could gather they have a repetitive history of such antics.

Apparently the site/business went down and then has come back but the matters have not changed?

In either case, given their track record, I'd like to avoid such a hassle and headache from a non-reputable source.

Even if I did order and received my product, I'd question it's authenticity and quality just based upon the reviews.

It is unfortunate but I don't think I'll be able to obtain as I can't find a reputable source.

I take it you hadn't read the post I made about them and discovery.

They don't have a stellar reputation it seems.

A quick google search could answer that as well. I'm little wary of ordering from them.

I'm assuming you called or emailed?

You're not the guy in charge of packaging and shipment, are you?

Take a look at their Turds and Convictions, sorry, Terms and Conditions (https://sciencelab.com/terms-conditions/), item 3 "Delivery and Performance":
Quote:
3.2 Product(s) ordered are considered special order item(s) by Seller because each product is fulfilled based on the customization of Purchaser´s order. Purchaser´s will be unable to cancel the item(s) for a refund. No refunds will be granted, all disputes will be denied and subject to additional fees. Seller will consider issuing a store credit or exchanging item(s) for a product of equal or greater value a restocking fee will likely be applied.  Store Credits are valid one (1) year from issue date.

Wow. If you complain and ask for a refund, they will deny it and charge you for the pleasure of having a refund denied. On the good side, they're honest about a "Purchaser's" being unable to cancel an order--because no one will hear the messages or read the e-mails.
