1-Bromo-3-(methylsulfonyl)-6,7-dihydrobenzo[c]thiophen-4(5H)-one CAS 882271-53-6

Description

The occurrence of 1-Bromo-3-(methylsulfonyl)-6,7-dihydrobenzo[c]thiophen-4(5H)-one is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-Bromo-3-(methylsulfonyl)-6,7-dihydrobenzo[c]thiophen-4(5H)-one (CAS 882271-53-6), a certified reference material (molecular formula C9H9BrO3S2, MW 309.20 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 1-Bromo-3-(methylsulfonyl)-6,7-dihydrobenzo[c]thiophen-4(5H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 309.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
