Description
CATO manufactures 5-Amino-3-bromo-2-hydroxybenzoic 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.
5-Amino-3-bromo-2-hydroxybenzoic acid (CAS 54669-99-7), molecular formula C7H6BrNO3 and molecular weight 232.03 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 5-Amino-3-bromo-2-hydroxybenzoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 232.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
