Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including methyl 4-bromo-3-(chlorosulfonyl)-5-fluorobenzoate.
CATO supplies methyl 4-bromo-3-(chlorosulfonyl)-5-fluorobenzoate (CAS 1249508-42-6), a certified reference material (molecular formula C8H5BrClFO4S, MW 331.54 g/mol) for analytical method development and quality control.
The molecular framework of methyl 4-bromo-3-(chlorosulfonyl)-5-fluorobenzoate (C8H5BrClFO4S) is characterized by a sulfone group, a carboxylic acid group, 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.
