6-Methyl-2,3-diphenylbenzo[b]thiophene CAS 25935-97-1

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.

6-Methyl-2,3-diphenylbenzo[b]thiophene (CAS 25935-97-1), molecular formula C21H16S and molecular weight 300.42 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to sulfur-containing functionality, a polycyclic aromatic system, 6-Methyl-2,3-diphenylbenzo[b]thiophene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 300.42 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).

CATO manufactures 6-Methyl-2,3-diphenylbenzo[b]thiophene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
