Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-[(4-Bromophenyl)sulfonylmethyl]benzoic acid.
CATO supplies 3-[(4-Bromophenyl)sulfonylmethyl]benzoic acid (CAS 142730-37-8), a certified reference material (molecular formula C14H11BrO4S, MW 355.20 g/mol) for analytical method development and quality control.
3-[(4-Bromophenyl)sulfonylmethyl]benzoic acid (C14H11BrO4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. It is notably hygroscopic, 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 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 3-[(4-Bromophenyl)sulfonylmethyl]benzoic acid 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.
