Chemical Structure

4-Boronobenzenesulfonic acid CAS 913836-00-7 chemical structure

Description

As a certified reference material (CRM), 4-Boronobenzenesulfonic 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.

4-Boronobenzenesulfonic acid (CAS 913836-00-7) is a high-purity analytical reference standard with the molecular formula C6H7BO5S and a molecular weight of 201.99 g/mol.

Structurally, 4-Boronobenzenesulfonic acid (C6H7BO5S) contains a carbohydrate-derived structure, a sulfone group. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 201.99 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.
