4-Bromo-3-chlorosulfonyl-benzoic acid CAS 50803-23-1

Description

The occurrence of 4-Bromo-3-chlorosulfonyl-benzoic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Bromo-3-chlorosulfonyl-benzoic acid (CAS 50803-23-1) is a high-purity analytical reference standard with the molecular formula C7H4BrClO4S and a molecular weight of 299.53 g/mol.

Structurally, 4-Bromo-3-chlorosulfonyl-benzoic acid (C7H4BrClO4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/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 299.53 g/mol, it falls into the medium-molecular-weight range. 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), 4-Bromo-3-chlorosulfonyl-benzoic 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.
