Structure of 3-Methyl-1H-pyrazole-5-carboxylic acid, CAS 696-22-0 — Structure · C5H6N2O2

CAS number: 696-22-0
Molecular formula: C₅H₆N₂O₂
Molecular weight: 126.11 g/mol
Standard packing: 1kg / 25kg / 100kg

CAS 696-22-0, 3-Methyl-1H-pyrazole-5-carboxylic acid, is a C5H6N2O2 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 C5H6N2O2 resolves to 5 carbons with 2 oxygens and 2 nitrogens. 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. The certificate states identity, assay and the analytical method used; a tighter limit than the catalogue entry can be written into the lot specification.
