Benzene-1,2-disulfonic acid CAS 31375-00-5

Description

Benzene-1,2-disulfonic acid (CAS 31375-00-5), molecular formula C14H12O and molecular weight 196.24 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Benzene-1,2-disulfonic acid (C14H12O) contains a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 196.24 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.

CATO manufactures Benzene-1,2-disulfonic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
