Chemical Structure
Description
CATO manufactures 3-(trifluoromethyl)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.
3-(trifluoromethyl)chromen-2-one (CAS 497959-34-9) is a high-purity analytical reference standard with the molecular formula C10H13F3O2 and a molecular weight of 222.20 g/mol.
The molecular framework of 3-(trifluoromethyl)chromen-2-one (C10H13F3O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
