The problem I see is that it looks like one can order salbutamol with 99% purity, from most places. Or am I looking at this the wrong way?
There are frequently high amounts of impurities in salbutamol. Look at this paper:
Quantitative determination of salbutamol sulfate impurities using achiral supercritical fluid chromatography
In the last years, supercritical fluid chromatography has largely been acknowledged as a singular and performing technique in the field of separation …
The present work focused on salbutamol sulfate and five specified related impurities, namely impurity B ((1RS)-2-[1,1-dimethylethyl(amino)]-1-(4-hydroxyphenyl)ethanol), impurity D (5-[(1RS)-2-[1,1-dimethylethyl(amino)]-1-hydroxyethyl]-2hydroxybenzaldéhyde), impurity F (1,1′-[oxybis[methylene(4-hydroxy-1,3-phenylene)]]bis[2-[(1,1-dimethylethyl)amino]ethanol]), impurity G (2-[benzyl-(1,1-dimethylethyl)amino]-1-[4-hydroxy-3-(hydroxymethyl)phenyl]ethanone) and impurity I ((1RS)-2-[1,1-dimethylethyl(amino)]-1-(3-hydroxymethyl)-4-[benzyloxyphenylethanol). The chemical structures are available in Supplementary data.

But you shared it so much appreciated. $120 is a small price to pay for piece of mind.

Thanks love
@janoshik
@Qingdao Sigma Chemicals -- I am glad you asked this specifically, I had the same question. Janoshik's answer was good, but I didn't 100% fully understand whether it was a "yes" or a "no" if it affects purity %. So I did some math myself:
Your test came out to 84.87% pure.
Salbutamol - 239.315 g/mol
Salbutamol Sulfate - 337.39 g/mol
Sulfate: 96.06 g/mol book value in isolation, 98.075 g/mol as combined with Salbutamol?
If it was artificially low because it didn't account for sulfate, then it would have captured 0.003546 moles of salbutamol per gram of sample ((0.8487 g salbutamol / 1 g sample) / 239.315 g/mol Salbutamol).
If this "0.003546 moles of salbutamol" was actually "0.003546 moles of salbutamol sulfate" then the active ingredient in 1 g of sample would weigh an extra 0.3478 grams (0.003546 moles * 98.075 g/mol Sulfate). This is *not possible* because then "1 gram of sample" would contain 1.196 grams of salbutamol sulfate -- obviously non-sensical.
So it looks like Janoshik definitely already correctly assumed some sort of counterion -- and while it didn't necessarily have to be sulfate, I cannot imagine what else anyone would ever assume for salbutamol.

I have financial gain involved. maybe 5% of it will be for me if even that high.
Don't take me as a saint, Dont wanna ruin my Rep
Yeah super recently, but a lot has changed since then. Lots more US domestic. Can't calculate prices correctly if I dont know what will be intl vs what will be domestic.

I hope you guys are enjoying the new lab tests we are posting on regular basis.
We are probably the first ones to test some products in Meso, never seen some testing on many peptides and raws that we tried.
We hope that you can suggest to us all the items that you think can be interesting to see some testing on them and we will be glad to put them on our list of planned lab tests.

Reship policy for Canada is easy
Either you use China Post or the Special line
if you pay the insurance 20% of total cost added you are eligibile for reship
if you don't pay it, you are not eligible for the reship.

Small price to pay in dealin with the overzealous CBSA....
Your efforts are massively appreciated. It's not ONLY that you're the only outfit offering most of these, and the only outfit TESTING most of these...it's also that you care about the tests and have been going back to your suppliers and asking "Why were these tests bad?" and going back to the tester (Jano) and asking "What contributed to these bad results?".
Really, thank you so much for setting the bar higher.
