3-Methyl-6,7-dihydrobenzo[b]thiophen-4(5H)-one CAS 33449-56-8

Description

The occurrence of 3-Methyl-6,7-dihydrobenzo[b]thiophen-4(5H)-one is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-Methyl-6,7-dihydrobenzo[b]thiophen-4(5H)-one (CAS 33449-56-8), a certified reference material (molecular formula C9H10OS, MW 166.24 g/mol) for analytical method development and quality control.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 3-Methyl-6,7-dihydrobenzo[b]thiophen-4(5H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 3-Methyl-6,7-dihydrobenzo[b]thiophen-4(5H)-one 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.
