Chemical Structure

3,4-Dimethylbenzene-1,2-diol CAS 2785-76-4 chemical structure

Description

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 supplies 3,4-Dimethylbenzene-1,2-diol (CAS 2785-76-4), a certified reference material (molecular formula C8H10O2, MW 138.16 g/mol) for analytical method development and quality control.

The molecular framework of 3,4-Dimethylbenzene-1,2-diol (C8H10O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures 3,4-Dimethylbenzene-1,2-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.
