Description
Compared with other compounds in its class, the molecular weight of 214.23 g/mol gives (3,3-difluorocyclopentyl)methyl methanesulfonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (3,3-difluorocyclopentyl)methyl methanesulfonate (CAS 1644679-78-6), a certified reference material (molecular formula C7H12F2O3S, MW 214.23 g/mol) for analytical method development and quality control.
The molecular framework of (3,3-difluorocyclopentyl)methyl methanesulfonate (C7H12F2O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), (3,3-difluorocyclopentyl)methyl methanesulfonate 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.
