3-fluoro-4-methylbenzene-1-sulfonyl chloride CAS 90260-13-2

Description

The occurrence of 3-fluoro-4-methylbenzene-1-sulfonyl chloride is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-fluoro-4-methylbenzene-1-sulfonyl chloride (CAS 90260-13-2), a certified reference material (molecular formula C7H12ClFO2S, MW 214.69 g/mol) for analytical method development and quality control.

3-fluoro-4-methylbenzene-1-sulfonyl chloride (C7H12ClFO2S) 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.
