Chemical Structure
Description
The occurrence of 4-Methyl-2-phenylbenzo[b]thiophene is closely related to sulfur-containing functionality, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Methyl-2-phenylbenzo[b]thiophene (CAS 162135-79-7), molecular formula C15H12S and molecular weight 224.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Methyl-2-phenylbenzo[b]thiophene (C15H12S) is characterized by sulfur-containing functionality, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
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 manufactures 4-Methyl-2-phenylbenzo[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.
