Folks,

I was looking for propionic acid (both to make esters/perfumes and to use as a solvent in nitrosations) and I found this website:

https://www.laboratoriumdiscounter.nl

I saw this website mentioned once in this section, but without any opinion. Has anyone already ordered anything from them? Any experience with delivery delays or purity of reagents? They don’t seem to be too costly, and have a fair range of alcohols/organic acids, which is nice to prepare esters.

Thanks!

They ship fast and have good prices, especially on their own brand chemicals.

I have ordered two times from them and my experience was good. Fast shipping and decent prices. I only ordered from their own brand chemicals (copper sulfate, hydrochloric acid 37%, sodium chlorite, potassium hydroxide, potassium chloride). Nothing really special, just replenishing stocks with cheap replacements. Purity of the materials is good.

Quite a few chemicals, however, are not shipped to private persons (e.g. nickel salts, cobalt salts, chloroform).

Ok, thanks a lot! I don't intend to buy anything fancy from them, just a couple of alcohols and organic acids and things of that ilk.
Basic stuff, the same as you. Thanks for the advice. Dank U veel!

labshop.nl is also a good shop for basic things. I would try to compare the prices but they are quite different - some things a more expensive, some things are less. The assortment is a modest one but the strong point is that usually everything is at home by the next day.

Their website is in Dutch only?

Yep, this is a usual thing for the internet shops here. The exceptions are extremely rare.
They speak English quite fluently by phone & email.

Agreed, but that doesn't make navigating the thing any simpler. By chance, German serves quite a lot, when you have learnt what the correspondances between Dutch (~ Platt Deutsch) and German (~ Hoch Deutsch) look like…

Well, my native language is Russian (also I can easily understand many eastern-european), so on this basis I can compare Dutch, German and English chemical nomenclature unbiased. And I would say that the Dutch looks quite OK for me, but German and English names for compounds look quite strange. (These unique names for elements like Sodium, Potassium, Tungsten in English for example, and when I try to search compounds on es-drie (it also only in German) web site I feel lack of a true gothic keyboard).

Of course German was an official language of chemistry in the past, so the most texts will be never translated, and now this is my motivation to study German - otherwise I think my knowledge of chemistry will never get a good basis.

But Dutch shops are easy to navigate for me - if I need Natrium I go to letter N.

Coming from French, English and German names are pretty familiar to me, but neither are Natrium, Kalium or Wolfram. Anyways, the differences are minor. French has also 'azote' instead of nitrogen. Anyways, thanks for the tip!

Apfelsäure, Schleimsäure... *cough*

Strange, I just got told about this shop very recently, and was astonished about the cheap prices for certain solvents.
Also, I got told it is a fine supplier.

Haven't ordered yet, but the damn prices!
Absolutely great!

Also a nice supplier, just be a bit careful when ordering chemicals they label is possible drug precursors, you might have to explain what you are planning on doing with them. Also some chemicals require an end user statement.

It is good chemistry knowledge to be informed of common alt names, at least for the most common stuff, like potassium(kalium), sodium(natrium), tungsten(wolfram), etc.

Whatever, copy-paste it to google and it will likely give you a lot of hints what it is better known to you.

Looked at the site and clicked on the letter P and first thing that I can see is palladium so I click on it and there is some very expensive palladium powder that looks very black.
My palladium powder is still a dull grey. I don't think it is supposed to be as dark
as it is in the picture . Then I clicked on propionic acid and it says €8 for a litre.
That sounds very cheap. I do not think I could buy it from China for that price. Then I clicked on acetic acid and its more expensive than the propionic acid then I clicked on platinum and for Pt powder there was the same black charcoal powder picture they had for Pd powder. These are what I would think are red flags usually but there's ppl above in the post saying that they have successfully ordered from there before so maybe they are all good.
Also if anyone wants platinum or palladium I can beat there prices by a lot. U2u for details if interested

Google has whole website translation while you use it, even easier. I have used it on Russian forums, even the posts are very readable that way.

Site looks nice, but they are more expensive than Onyxmet.

And under 'Elements' there are some errors: https://www.laboratoriumdiscounter.nl/en/chemicals/elements/

wrong symbols for two elements. F = Phosphorus, Pd = Lead ???

Some hint. When I need to know the name of a compound in different language I just go to wikipedia on this language (let say, wikipedia.de) enter the compound formula (let say, H2SO4), press "search" and then I get the compound article with the name as a title (Schwefelsäure).

In wiki, you can also just move your cursor over different languages and see the name of the page.

There are also some details of interest in different language, for example I like to check German wiki because sometimes it has some nice data about compounds and reactions that English doesn't.

I’m not sure I'd judge the purity of a powder out of a picture. There are too many parameters that can go wrong in colour rendition for it to be a good tell-tale of quality. Besides, it might just be a generic picture – spilling out platinum or palladium powder just to take a picture is taking a risk of losing some, to quite an appreciate financial loss.

Properly what I wanted. I’m pretty happy with their prices for propionic acid and isopropyl alcohol that I use for household cleaning, too.

Obviously they are no chemist's, phosphorus in Dutch is fosfor. Maybe the also have wrong pictures for some of their compounds, for example the palladium.

I got a bottle of their barium hydroxide, I believe the label said it was the octahydrate, and when I obviously used too much it turned out be the monohydrate, while the CAS number was for the anhydrate...

Reference pictures are just.. reference. Any white, grey or black powder will look just like that, same goes for any colorless liquid. Easier to just leave the pics off, because no one really cares about looking at those.

But messing up with hydrates and CAS numbers is a more serious matter in my books.

I agree. I've ordered a couple of commonplace chemicals. I’ll see what I get. Thanks for your inputs.

Ah, I just checked that bottle, the CAS was correct for the monohydrate label, but it turned out to be the octahydrate...anyway, it was mislabeled.
