Chemical Structure
Description
The molecular framework of 1-(2,2-Difluoro-1-methylcyclopropyl)ethan-1-one (C6H8F2O) is characterized by 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.
1-(2,2-Difluoro-1-methylcyclopropyl)ethan-1-one (CAS 128073-32-5) is a high-purity analytical reference standard with the molecular formula C6H8F2O and a molecular weight of 134.12 g/mol.
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), 1-(2,2-Difluoro-1-methylcyclopropyl)ethan-1-one 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.
