Chemical Structure

(<I>R</I>)-(+)-Methyl p-toluene sulfoxide CAS 1519-39-7 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.

(<I>R</I>)-(+)-Methyl p-toluene sulfoxide (CAS 1519-39-7) is a high-purity analytical reference standard with the molecular formula C8H16OS and a molecular weight of 160.28 g/mol.

The molecular framework of (<I>R</I>)-(+)-Methyl p-toluene sulfoxide (C8H16OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage. 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 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.
