4,5-Bis(methylthio)-1,3-dithiole-2-thione CAS 49638-64-4

Description

4,5-Bis(methylthio)-1,3-dithiole-2-thione (CAS 49638-64-4), molecular formula C5H6S5 and molecular weight 226.43 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4,5-Bis(methylthio)-1,3-dithiole-2-thione (C5H6S5) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

As a certified reference material (CRM), 4,5-Bis(methylthio)-1,3-dithiole-2-thione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
