Chemical Structure

2-Mercaptobenzene-1,4-diol CAS 2889-61-4 chemical structure

Description

The occurrence of 2-Mercaptobenzene-1,4-diol 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.

CATO supplies 2-Mercaptobenzene-1,4-diol (CAS 2889-61-4), a certified reference material (molecular formula C6H6O2S, MW 142.18 g/mol) for analytical method development and quality control.

Based on its molecular formula C6H6O2S, 2-Mercaptobenzene-1,4-diol contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 142.18 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.

CATO manufactures 2-Mercaptobenzene-1,4-diol 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.
