3,5-Dimethylbenzene-1,2-diol CAS 2785-75-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,5-Dimethylbenzene-1,2-diol.

3,5-Dimethylbenzene-1,2-diol (CAS 2785-75-3) is a high-purity analytical reference standard with the molecular formula C8H10O2 and a molecular weight of 138.16 g/mol.

The molecular framework of 3,5-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).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
