Description
As a certified reference material (CRM), N-benzyl-2-(7-benzyl-8-oxo-2-phenyl-7,8-dihydro-9H-purin-9-yl)-N-ethylacetamide 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.
N-benzyl-2-(7-benzyl-8-oxo-2-phenyl-7,8-dihydro-9H-purin-9-yl)-N-ethylacetamide (CAS 1359705-67-1), molecular formula C29H27N5O2 and molecular weight 477.56 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-benzyl-2-(7-benzyl-8-oxo-2-phenyl-7,8-dihydro-9H-purin-9-yl)-N-ethylacetamide (C29H27N5O2) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
