Chemical Structure

5-Mercapto-4-phenyl-3H-1,2-dithiole-3-thione CAS 16101-90-9 chemical structure

Description

The molecular framework of 5-Mercapto-4-phenyl-3H-1,2-dithiole-3-thione (C9H6S4) 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 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).

CATO supplies 5-Mercapto-4-phenyl-3H-1,2-dithiole-3-thione (CAS 16101-90-9), a certified reference material (molecular formula C9H6S4, MW 242.40 g/mol) for analytical method development and quality control.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
