SuppliedForm

Description

A purchasable form of an ingredient: what a lab would physically order and receive. Separate from `ChemicalProperties`, which describes the substance the record denotes — the two differ whenever a recipe names a substance generically but only one form is sold, or several are.

Name: name
Description: The product name as a catalogue would write it, e.g. `Carboxymethylcellulose sodium`. Not necessarily the record's preferred_term, which optimises for readability in the graph.

Cas rn

Name: cas_rn
Description: The CAS-RN you would order by. This is the operative identifier for procurement and may differ from `chemical_properties.cas_rn`, which describes the substance — the free acid and its sodium salt have different CAS-RNs and are different purchases.
