Structure of 2-(3-Methyl-1,2-oxazol-5-yl)acetic acid, CAS 19668-85-0 — Structure · C6H7NO3

CAS number: 19668-85-0
Molecular formula: C₆H₇NO₃
Molecular weight: 141.12 g/mol
Standard packing: 1kg / 25kg / 100kg

CAS 19668-85-0, 2-(3-Methyl-1,2-oxazol-5-yl)acetic acid, is a C6H7NO3 acid supplied in kilogram lots with a batch COA.

The carboxylic acid is activated in situ for amidation or esterification, or used directly for salt formation; the free acid is also the form that stores best. The methyl branch at C3 changes how the chain packs, which shows up in melting behaviour and in the solubility of the free material.

The formula C6H7NO3 resolves to 6 carbons with 3 oxygens and one nitrogen. Short-chain entries of this size are volatile enough that headspace and packing matter: the lot is shipped in sealed units and opened in a fume hood.

Handling and storage

Acids are stored away from amines and bases, and the container is kept closed because the material is hygroscopic.

Ordering

The unit weights held are 1kg / 25kg / 100kg. A split shipment across two of those sizes is treated as one lot and one certificate. Identity is confirmed by NMR and MS at release, and the assay value belongs to the lot rather than to the catalogue entry.
