Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromo-4-(trifluoromethyl)benzenesulfinic acid sodium salt.
2-Bromo-4-(trifluoromethyl)benzenesulfinic acid sodium salt (CAS 1233513-49-9), molecular formula C7H3BrF3O2SNa and molecular weight 311.05 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a salt form, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system, 2-Bromo-4-(trifluoromethyl)benzenesulfinic acid sodium salt is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 311.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
