2,5-Dimethyl-4-hydroxy-3(2H)-furanone CAS 3658-77-3 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

2,5-Dimethyl-4-hydroxy-3(2H)-furanone (CAS 3658-77-3) is a high-purity analytical reference standard with the molecular formula C6H8O3 and a molecular weight of 128.13 g/mol.

2,5-Dimethyl-4-hydroxy-3(2H)-furanone (C6H8O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 2,5-Dimethyl-4-hydroxy-3(2H)-furanone 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.
