Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 176.57 g/mol gives 2,2-difluorocyclopropanesulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,2-difluorocyclopropanesulfonyl chloride (CAS 1935280-15-1) is a high-purity analytical reference standard with the molecular formula C3H3ClF2O2S and a molecular weight of 176.57 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2,2-difluorocyclopropanesulfonyl chloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 176.57 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.
