[(1S)-3,3-difluorocyclopentyl]methanesulfonyl chloride (CAS 2381424-50-4) is a high-purity analytical reference standard with the molecular formula C6H9ClF2O2S and a molecular weight of 218.65 g/mol.
[(1S)-3,3-difluorocyclopentyl]methanesulfonyl chloride (C6H9ClF2O2S) 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.
As a certified reference material (CRM), [(1S)-3,3-difluorocyclopentyl]methanesulfonyl 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.
