Labelling requirements for research chemicals — the long version

Posting this under the heading it deserves: Labelling requirements for research chemicals — the long version Everything below is what sits behind that.

I would like to talk about documentation quality as a signal, separately from product quality.

Across the certificates I have collected, the variation in what is disclosed is much larger than the variation in the purity figures. Some name the analytical procedure; some give a number and a signature.

My hypothesis is that disclosure correlates with process control, and I would like to know whether the people who audit paperwork for a living think that is naive.

Off-label use and medical practice: clinicians can prescribe approved medications off-label under some circumstances. That is different from research-use-only compounds, which are not approved for any human use.

Primary documents matter: regulatory positions are published in official documents. Reading the regulatory agency's website directly is more reliable than reading a forum summary of it.
