[1-(trifluoromethyl)cyclopropyl]methanesulfonyl chloride CAS 1228450-49-4

Description

Compared with other compounds in its class, the molecular weight of 222.61 g/mol gives [1-(trifluoromethyl)cyclopropyl]methanesulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

[1-(trifluoromethyl)cyclopropyl]methanesulfonyl chloride (CAS 1228450-49-4), molecular formula C5H6ClF3O2S and molecular weight 222.61 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, [1-(trifluoromethyl)cyclopropyl]methanesulfonyl chloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 222.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
