Description
CATO supplies 4-(4-(3-Chlorophenyl)-4-(pyrrolidine-1-carbonyl)piperidin-1-yl)-1-(4-fluorophenyl)butan-1-one oxalate (CAS 2256-06-6), a certified reference material (molecular formula C26H30ClFN2O2C2H2O4, MW 547.02 g/mol) for analytical method development and quality control.
The molecular framework of 4-(4-(3-Chlorophenyl)-4-(pyrrolidine-1-carbonyl)piperidin-1-yl)-1-(4-fluorophenyl)butan-1-one oxalate (C26H30ClFN2O2C2H2O4) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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.
As a certified reference material (CRM), 4-(4-(3-Chlorophenyl)-4-(pyrrolidine-1-carbonyl)piperidin-1-yl)-1-(4-fluorophenyl)butan-1-one oxalate 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.
