1-(Difluoromethyl)cyclopropane-1-sulfonyl chloride CAS 2091793-00-7

Description

Compared with other compounds in its class, the molecular weight of 190.60 g/mol gives 1-(Difluoromethyl)cyclopropane-1-sulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(Difluoromethyl)cyclopropane-1-sulfonyl chloride (CAS 2091793-00-7), molecular formula C4H5ClF2O2S and molecular weight 190.60 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-(Difluoromethyl)cyclopropane-1-sulfonyl chloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 190.60 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 1-(Difluoromethyl)cyclopropane-1-sulfonyl chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
