Chemical Structure
Description
3,4,8-Trimethyl-7-[(oxiran-2-yl)methoxy]-2h-chromen-2-one (CAS 866240-05-3), molecular formula C15H16O4 and molecular weight 260.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3,4,8-Trimethyl-7-[(oxiran-2-yl)methoxy]-2h-chromen-2-one (C15H16O4) 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.
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 3,4,8-Trimethyl-7-[(oxiran-2-yl)methoxy]-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.
