Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Benzhydryl-6-methyl-8-oxa-2,5-diazaspiro[3.5]Nonane (CAS 1639963-80-6), molecular formula C20H24N2O and molecular weight 308.42 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Benzhydryl-6-methyl-8-oxa-2,5-diazaspiro[3.5]Nonane (C20H24N2O) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 2-Benzhydryl-6-methyl-8-oxa-2,5-diazaspiro[3.5]Nonane 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.
