Chemical Structure
Description
As a certified reference material (CRM), 2-Bromo-4-aminobenzoic 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-Bromo-4-aminobenzoic Acid (CAS 2486-52-4), molecular formula C7H6BrNO2 and molecular weight 216.03 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Bromo-4-aminobenzoic Acid (C7H6BrNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 216.03 g/mol, it falls into the medium-molecular-weight range. 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.
