Description
As a certified reference material (CRM), 2-Amino-3-bromo-5-methylbenzoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
2-Amino-3-bromo-5-methylbenzoic acid (CAS 13091-43-5) is a high-purity analytical reference standard with the molecular formula C8H14BrNO2 and a molecular weight of 236.11 g/mol.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 2-Amino-3-bromo-5-methylbenzoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 236.11 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.
