Chemical Structure

1,1-Bis(methylthio)ethylene CAS 51102-74-0 chemical structure

Description

The occurrence of 1,1-Bis(methylthio)ethylene is closely related to sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,1-Bis(methylthio)ethylene (CAS 51102-74-0) is a high-purity analytical reference standard with the molecular formula C4H8S2 and a molecular weight of 120.24 g/mol.

The molecular framework of 1,1-Bis(methylthio)ethylene (C4H8S2) is characterized by sulfur-containing functionality. 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.

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.
