3-Chloro-5-methoxy-6-methylbenzo-[b]thiophene-2-carbonyl chloride CAS 802908-64-1

Description

Compared with other compounds in its class, the molecular weight of 275.15 g/mol gives 3-Chloro-5-methoxy-6-methylbenzo-[b]thiophene-2-carbonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Chloro-5-methoxy-6-methylbenzo-[b]thiophene-2-carbonyl chloride (CAS 802908-64-1) is a high-purity analytical reference standard with the molecular formula C11H8Cl2O2S and a molecular weight of 275.15 g/mol.

3-Chloro-5-methoxy-6-methylbenzo-[b]thiophene-2-carbonyl chloride (C11H8Cl2O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
