Description
CATO manufactures 3,3'-((2-Chlorophenyl)methylene)bis(4-hydroxy-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.
CATO supplies 3,3'-((2-Chlorophenyl)methylene)bis(4-hydroxy-2h-chromen-2-one) (CAS 4322-58-1), a certified reference material (molecular formula C25H15ClO6, MW 446.84 g/mol) for analytical method development and quality control.
The molecular framework of 3,3'-((2-Chlorophenyl)methylene)bis(4-hydroxy-2h-chromen-2-one) (C25H15ClO6) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
