1-Methoxy-2-methyl-4-(methylsulfonyl)benzene CAS 50390-79-9

Description

Compared with other compounds in its class, the molecular weight of 200.25 g/mol gives 1-Methoxy-2-methyl-4-(methylsulfonyl)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-Methoxy-2-methyl-4-(methylsulfonyl)benzene (CAS 50390-79-9), a certified reference material (molecular formula C9H12O3S, MW 200.25 g/mol) for analytical method development and quality control.

The molecular framework of 1-Methoxy-2-methyl-4-(methylsulfonyl)benzene (C9H12O3S) is characterized by a sulfone group, 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.
