Chemical Structure

1-Chloro-6,6-dimethyl-3-(methylthio)-6,7-dihydrobenzo[c]thiophen-4(5H)-one CAS 175202-90-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 260.80 g/mol gives 1-Chloro-6,6-dimethyl-3-(methylthio)-6,7-dihydrobenzo[c]thiophen-4(5H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-Chloro-6,6-dimethyl-3-(methylthio)-6,7-dihydrobenzo[c]thiophen-4(5H)-one (CAS 175202-90-1), molecular formula C11H13ClOS2 and molecular weight 260.80 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 1-Chloro-6,6-dimethyl-3-(methylthio)-6,7-dihydrobenzo[c]thiophen-4(5H)-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 260.80 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.

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.
