1-(3-Chloro-6-fluorobenzo[b]thiophen-2-yl)ethanone CAS 937642-21-2

Description

The occurrence of 1-(3-Chloro-6-fluorobenzo[b]thiophen-2-yl)ethanone is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(3-Chloro-6-fluorobenzo[b]thiophen-2-yl)ethanone (CAS 937642-21-2), molecular formula C10H6ClFOS and molecular weight 228.67 g/mol, is a CATO reference standard with documented purity and traceability.

1-(3-Chloro-6-fluorobenzo[b]thiophen-2-yl)ethanone (C10H6ClFOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
