Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3,5-Dimethyl-2,6-diphenylpiperidin-4-one (CAS 5707-11-9), a certified reference material (molecular formula C19H21NO, MW 279.38 g/mol) for analytical method development and quality control.
The molecular framework of 3,5-Dimethyl-2,6-diphenylpiperidin-4-one (C19H21NO) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 3,5-Dimethyl-2,6-diphenylpiperidin-4-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.
