Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Hydroxy-2-trifluoromethyl-pent-4-ynoic acid methyl ester (CAS 537034-30-3) is a high-purity analytical reference standard with the molecular formula C7H7F3O3 and a molecular weight of 196.12 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 2-Hydroxy-2-trifluoromethyl-pent-4-ynoic acid methyl ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 196.12 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).
CATO manufactures 2-Hydroxy-2-trifluoromethyl-pent-4-ynoic acid methyl ester under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
