  How to know quality of a chemical?

  Posted by VitalikButerin on March 2, 2019 at 10:19 am

  I understand people will say ‘just buy it from a reputable seller’… That is not always the case..

  I bought two carrot oil’s from a two very reputable sellers, both different of course - i believed one to be purer than the other, although both claimed same % purity… However, thats not the point right now.

  Let’s say I’d like to buy Allantoin from a second source, a lesser known manufacturer, or any other chemical in fact - how can we know their ‘stuff is good’ ? 

  i’ve been told that doing tests are limited in the lab
