6,8-Dichloro-2-phenyl-3,4-dihydro-2h-1-benzopyran-4-one CAS 100965-49-9 chemical structure

Description

The occurrence of 6,8-Dichloro-2-phenyl-3,4-dihydro-2h-1-benzopyran-4-one is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 6,8-Dichloro-2-phenyl-3,4-dihydro-2h-1-benzopyran-4-one (CAS 100965-49-9), a certified reference material (molecular formula C15H10Cl2O2, MW 293.14 g/mol) for analytical method development and quality control.

6,8-Dichloro-2-phenyl-3,4-dihydro-2h-1-benzopyran-4-one (C15H10Cl2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 6,8-Dichloro-2-phenyl-3,4-dihydro-2h-1-benzopyran-4-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.
