Description
CATO manufactures 2,5-Bis(bromomethyl)benzenesulfonic 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.
CATO supplies 2,5-Bis(bromomethyl)benzenesulfonic acid (CAS 1204-10-0), a certified reference material (molecular formula C8H8Br2O3S, MW 344.02 g/mol) for analytical method development and quality control.
2,5-Bis(bromomethyl)benzenesulfonic acid (C8H8Br2O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
