Chemical Structure

3-Acetyl-7-acetyloxy-5-hydroxy-2-methyl-4H-1-benzopyran-4-one CAS 7338-52-5 chemical structure

Description

The occurrence of 3-Acetyl-7-acetyloxy-5-hydroxy-2-methyl-4H-1-benzopyran-4-one is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Acetyl-7-acetyloxy-5-hydroxy-2-methyl-4H-1-benzopyran-4-one (CAS 7338-52-5), molecular formula C14H12O6 and molecular weight 276.24 g/mol, is a CATO reference standard with documented purity and traceability.

3-Acetyl-7-acetyloxy-5-hydroxy-2-methyl-4H-1-benzopyran-4-one (C14H12O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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).

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

CATO manufactures 3-Acetyl-7-acetyloxy-5-hydroxy-2-methyl-4H-1-benzopyran-4-one 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.
