Chemical Structure

(E)-6-methyl-2-(4-styrylphenyl)benzo[b]thiophene CAS 22786-00-1 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.

(E)-6-methyl-2-(4-styrylphenyl)benzo[b]thiophene (CAS 22786-00-1), molecular formula C23H18S and molecular weight 326.45 g/mol, is a CATO reference standard with documented purity and traceability.

(E)-6-methyl-2-(4-styrylphenyl)benzo[b]thiophene (C23H18S) contains sulfur-containing functionality, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 (E)-6-methyl-2-(4-styrylphenyl)benzo[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.
