Chemical Structure

6'-Ethyl-10'-hydroxy-3',4'-dihydro-8'h-spiro[cyclohexane-1,2'-pyrano[3,2-g]chromen]-8'-one CAS 919744-57-3 chemical structure

Description

6'-Ethyl-10'-hydroxy-3',4'-dihydro-8'h-spiro[cyclohexane-1,2'-pyrano[3,2-g]chromen]-8'-one (CAS 919744-57-3) is a high-purity analytical reference standard with the molecular formula C19H22O4 and a molecular weight of 314.38 g/mol.

The molecular framework of 6'-Ethyl-10'-hydroxy-3',4'-dihydro-8'h-spiro[cyclohexane-1,2'-pyrano[3,2-g]chromen]-8'-one (C19H22O4) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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