Description
As a certified reference material (CRM), 1-Chloro-1,1-difluoro-3-phenylpropan-2-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.
1-Chloro-1,1-difluoro-3-phenylpropan-2-one (CAS 86340-72-9), molecular formula C9H7ClF2O and molecular weight 204.60 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Chloro-1,1-difluoro-3-phenylpropan-2-one (C9H7ClF2O) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
