4-Hydroxy-2-(hydroxymethyl)cyclopent-2-en-1-one (CAS 76374-26-0), molecular formula C6H8O3 and molecular weight 128.13 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 4-Hydroxy-2-(hydroxymethyl)cyclopent-2-en-1-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 128.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
