Chemical Structure
Description
The molecular framework of 1,3-Bis(methylthio)benzene (C8H10S2) is characterized by sulfur-containing functionality, 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).
1,3-Bis(methylthio)benzene (CAS 2388-69-4) is a high-purity analytical reference standard with the molecular formula C8H10S2 and a molecular weight of 170.29 g/mol.
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.
