Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including rac-2-Methyl-2,3-epoxy-4-phenyl-4H-pyrano[3,2-c]benzopyran-5-one.
rac-2-Methyl-2,3-epoxy-4-phenyl-4H-pyrano[3,2-c]benzopyran-5-one (CAS 1217816-92-6), molecular formula C19H14O4 and molecular weight 306.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of rac-2-Methyl-2,3-epoxy-4-phenyl-4H-pyrano[3,2-c]benzopyran-5-one (C19H14O4) 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 rac-2-Methyl-2,3-epoxy-4-phenyl-4H-pyrano[3,2-c]benzopyran-5-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.
