Description
CATO supplies 2,4-dichloro-6-formylphenyl 2,6-difluorobenzoate (CAS 646989-40-4), a certified reference material (molecular formula C14H6Cl2F2O3, MW 331.10 g/mol) for analytical method development and quality control.
The molecular framework of 2,4-dichloro-6-formylphenyl 2,6-difluorobenzoate (C14H6Cl2F2O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 2,4-dichloro-6-formylphenyl 2,6-difluorobenzoate 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.
