(2-chloro-6-fluorophenyl)methanesulphonyl chloride CAS 926257-07-0

Description

Compared with other compounds in its class, the molecular weight of 249.13 g/mol gives (2-chloro-6-fluorophenyl)methanesulphonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(2-chloro-6-fluorophenyl)methanesulphonyl chloride (CAS 926257-07-0), molecular formula C7H11Cl2FO2S and molecular weight 249.13 g/mol, is a CATO reference standard with documented purity and traceability.

(2-chloro-6-fluorophenyl)methanesulphonyl chloride (C7H11Cl2FO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
