Compound comparisons
Some compounds are frequently discussed together. These pages set out what the published literature examines in each, in what study material, and what each latest published report assayed — side by side, so the differences are visible rather than asserted. None of them says which compound is preferable for any purpose, and nothing on this site does.
A pairing is published only where both compounds carry a third-party certificate. A comparison that cannot show a measured purity for one column is not a comparison worth making, so it is not made.
Specification comparisons
Identifiers and report status side by side, from the specification records.
