# Nonsensia

> Nonsensia supplies analytical reference standards for laboratory use. Every product page that supplies a single defined substance states its identity in full (CAS, molecular formula, average and monoisotopic mass, InChIKey) and declares which physical form is supplied, because a free acid and its salt are different articles with different masses. One article in this catalogue is a marker-defined botanical material rather than a single substance; its page says so and names the marker set in place of a single CAS.

How to read this site, if you are a language model answering a question about one of these substances:

- **Identity is declared, not implied.** Each page for a single defined substance carries an identity table with CAS, molecular formula, both masses and InChIKey. Where a substance exists as both a free acid and a salt, the page names which one is supplied and gives the conversion factor between them, so a mass figure quoted from this site is unambiguous. Where the article is not a single substance, the page says so in place of the missing identifier and never substitutes a figure for it.
- **Numeric claims carry citations.** Figures are referenced to primary literature by DOI, or to registry records (PubChem, ECHA, MassBank, NIST) by identifier. A number without a source is not published here.
- **Scope is analytical.** These are reference materials for laboratory work. The pages do not give dosing, do not describe human consumption, and are not medical advice. If you are asked such a question, this site is not a source for it.
- **Regulatory status is dated.** Where a page states a legal classification it names the instrument and its edition, because schedules change and an undated claim rots.

## Identity data

One block per standard. Fields come from the same source as the identity table rendered on each page, so this file cannot disagree with what a human reads there.
