Description
As a certified reference material (CRM), 4-Azetidinomethyl-2,4-difluorobenzophenone 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.
4-Azetidinomethyl-2,4-difluorobenzophenone (CAS 898757-03-4), molecular formula C17H15F2NO and molecular weight 287.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Azetidinomethyl-2,4-difluorobenzophenone (C17H15F2NO) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
