Chemical Structure

6-Bromo-2,2-dimethylbenzo[b]thiophen-3(2H)-one 1,1-dioxide CAS 1240288-82-7 chemical structure

Description

The occurrence of 6-Bromo-2,2-dimethylbenzo[b]thiophen-3(2H)-one 1,1-dioxide 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.

6-Bromo-2,2-dimethylbenzo[b]thiophen-3(2H)-one 1,1-dioxide (CAS 1240288-82-7) is a high-purity analytical reference standard with the molecular formula C10H9BrO3S and a molecular weight of 289.15 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 6-Bromo-2,2-dimethylbenzo[b]thiophen-3(2H)-one 1,1-dioxide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 289.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
