Chemical Structure

3,6-Dichloro-7-hydroxy-4-methyl-2h-chromen-2-one CAS 53391-75-6 chemical structure

Description

CATO manufactures 3,6-Dichloro-7-hydroxy-4-methyl-2h-chromen-2-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.

3,6-Dichloro-7-hydroxy-4-methyl-2h-chromen-2-one (CAS 53391-75-6) is a high-purity analytical reference standard with the molecular formula C10H6Cl2O3 and a molecular weight of 245.06 g/mol.

3,6-Dichloro-7-hydroxy-4-methyl-2h-chromen-2-one (C10H6Cl2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
