2-Hydroxy-4-methylbenzenesulfonic acid CAS 22356-80-5

Description

The occurrence of 2-Hydroxy-4-methylbenzenesulfonic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Hydroxy-4-methylbenzenesulfonic acid (CAS 22356-80-5) is a high-purity analytical reference standard with the molecular formula C7H8O4S and a molecular weight of 188.20 g/mol.

Structurally, 2-Hydroxy-4-methylbenzenesulfonic acid (C7H8O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 188.20 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
