Chemical Structure
Description
As a certified reference material (CRM), 3,3-Difluorocyclobutanone 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.
3,3-Difluorocyclobutanone (CAS 1273564-99-0) is a high-purity analytical reference standard with the molecular formula C4H4F2O and a molecular weight of 106.07 g/mol.
The molecular framework of 3,3-Difluorocyclobutanone (C4H4F2O) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
