1-Chloro-4-((4-fluorophenyl)sulfonyl)benzene CAS 565-23-1

Description

The occurrence of 1-Chloro-4-((4-fluorophenyl)sulfonyl)benzene is closely related to a sulfone group, a carboxylic acid group, 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-Chloro-4-((4-fluorophenyl)sulfonyl)benzene (CAS 565-23-1), molecular formula C12H8ClFO2S and molecular weight 270.71 g/mol, is a CATO reference standard with documented purity and traceability.

1-Chloro-4-((4-fluorophenyl)sulfonyl)benzene (C12H8ClFO2S) contains a sulfone group, a carboxylic acid group, 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, 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.
