Where it is sold
This site links to no seller today, so the table below is empty. The moment any outbound store link appears on this page, three things ship in the same deploy: the link carries rel="sponsored nofollow", a visible disclosure sits beside it naming the relationship as common ownership rather than a commission, and the same disclosure goes into the footer of every page. That is written down in the editorial policy before there is anything to disclose, which is the only time such a commitment is worth making.

How to read a price in this market
For most compounds on this site a certificate of analysis has nothing external to be checked against. This one is different: a pharmacopoeial standard exists. That raises what a good certificate could establish, and it also raises the bar, because the documented impurity classes for this molecule include isomers and dimers that a simple purity figure will not separate.
A price says what a seller decided to charge. It does not say which standard a material was made to, whether the analysis behind a certificate could resolve the impurities that matter, or whether the certificate corresponds to the vial in front of you.
What a certificate of analysis proves, and what it does not, is covered in the sourcing section of the evidence review.
Frequently asked questions
Why does this page not list prices?
This site sells nothing and publishes no prices or vendor comparisons. Naming a price alongside a compound moves a page from documenting something to marketing it.
Does a certificate of analysis mean more for this compound than for others?
It can, because a pharmacopoeial reference standard exists for this molecule and most compounds on this site have none. It also has to do more work: 23 related impurities above 0.1 mg per gram were identified in that standard, including isomers and dimers.
