Chemical Structure
Description
CATO supplies 2-Amino-4-bromo-5-chlorobenzoic acid (CAS 150812-32-1), a certified reference material (molecular formula C7H5BrClNO2, MW 250.48 g/mol) for analytical method development and quality control.
2-Amino-4-bromo-5-chlorobenzoic acid (C7H5BrClNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), 2-Amino-4-bromo-5-chlorobenzoic 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.
