CATO supplies 8-(4-Bromophenyl)-6,7-dimethyl-7,8-dihydro-6H-[1,3]dioxolo[4,5-g]chromen-6-ol (CAS 1212202-17-9), a certified reference material (molecular formula C18H17BrO4, MW 377.23 g/mol) for analytical method development and quality control.
The molecular framework of 8-(4-Bromophenyl)-6,7-dimethyl-7,8-dihydro-6H-[1,3]dioxolo[4,5-g]chromen-6-ol (C18H17BrO4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
