Chemical Structure
Description
CATO supplies 1-Bromo-5-chloro-2-fluoro-4-methoxybenzene (CAS 901236-75-7), a certified reference material (molecular formula C7H5BrClFO, MW 239.47 g/mol) for analytical method development and quality control.
The molecular framework of 1-Bromo-5-chloro-2-fluoro-4-methoxybenzene (C7H5BrClFO) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system. 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).
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 1-Bromo-5-chloro-2-fluoro-4-methoxybenzene 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.
