Seeking a US source for sodium nitrite that ships residential
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.

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

I just called Chem-Impex and was told they only ship to commercial addresses.
You can’t claim you drank all day if you didn’t start early in the morning.

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

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.

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.

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

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€

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
https://www.complaintsboard.com/reviews/sciencelabcom-a17157... - numerous complaints of non-shipment, refund issues, back order issues, lack of
communication.
https://www.resellerratings.com/store/ScienceLab with a 1.0 and 1 star rating
sciencelab.com doesn't seem all that promising on first impression and makes me wary of wanting to deal with a headache
