Chemical Structure
Description
The molecular framework of 10-Methoxy-8,8-dimethyl-2H,8H-pyrano[3,2-g]chromen-2-one (C15H14O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. 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.
CATO supplies 10-Methoxy-8,8-dimethyl-2H,8H-pyrano[3,2-g]chromen-2-one (CAS 483-92-1), a certified reference material (molecular formula C15H14O4, MW 258.27 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
