Description
CATO manufactures 2-Amino-4-bromo-6-nitrobenzoic 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.
2-Amino-4-bromo-6-nitrobenzoic acid (CAS 1167056-67-8) is a high-purity analytical reference standard with the molecular formula C7H5BrN2O4 and a molecular weight of 261.03 g/mol.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 2-Amino-4-bromo-6-nitrobenzoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 261.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
