Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2-methyl-3-oxocyclopentyl)acetic acid.
2-(2-methyl-3-oxocyclopentyl)acetic acid (CAS 57026-65-0), molecular formula C8H12O3 and molecular weight 156.18 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(2-methyl-3-oxocyclopentyl)acetic acid (C8H12O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 156.18 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
