Chemical Structure
Description
The occurrence of 7-Hydroxy-2,8-dimethyl-3-(o-tolyl)-4h-chromen-4-one is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 7-Hydroxy-2,8-dimethyl-3-(o-tolyl)-4h-chromen-4-one (CAS 315233-70-6), a certified reference material (molecular formula C18H16O3, MW 280.32 g/mol) for analytical method development and quality control.
7-Hydroxy-2,8-dimethyl-3-(o-tolyl)-4h-chromen-4-one (C18H16O3) contains a steroid core, a hydroxyl group, an ether linkage. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 7-Hydroxy-2,8-dimethyl-3-(o-tolyl)-4h-chromen-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.
