Chemical Structure

1,2-Bis(phenylthio)ethene CAS 23528-44-1 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.

CATO supplies 1,2-Bis(phenylthio)ethene (CAS 23528-44-1), a certified reference material (molecular formula C14H12S2, MW 244.38 g/mol) for analytical method development and quality control.

Owing to sulfur-containing functionality, a polycyclic aromatic system, 1,2-Bis(phenylthio)ethene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 244.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

As a certified reference material (CRM), 1,2-Bis(phenylthio)ethene 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.
