3,5-Dichloro-4-methylthiophenol CAS 1803729-13-6

Description

CATO supplies 3,5-Dichloro-4-methylthiophenol (CAS 1803729-13-6), a certified reference material (molecular formula C7H6Cl2S, MW 193.09 g/mol) for analytical method development and quality control.

Structurally, 3,5-Dichloro-4-methylthiophenol (C7H6Cl2S) contains sulfur-containing functionality, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 193.09 g/mol, it falls into the medium-molecular-weight range. 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), 3,5-Dichloro-4-methylthiophenol 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.
