Chemical Structure

2H-1-Benzopyran-3-carboxaldehyde,2-phenyl- CAS 57543-47-2 chemical structure

Description

2H-1-Benzopyran-3-carboxaldehyde,2-phenyl- (CAS 57543-47-2), molecular formula C16H12O2 and molecular weight 236.27 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2H-1-Benzopyran-3-carboxaldehyde,2-phenyl- (C16H12O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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.

CATO manufactures 2H-1-Benzopyran-3-carboxaldehyde,2-phenyl- 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.
