Chemical Structure

2-Bromobenzoic Acid CAS 88-65-3 chemical structure

Description

2-Bromobenzoic Acid (CAS 88-65-3), molecular formula C7H5BrO2 and molecular weight 201.02 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H5BrO2, 2-Bromobenzoic Acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 201.02 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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-Bromobenzoic 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.
