(E)-2-(9-Benzyl-9H-purin-6-yl)-N,N-diethylethenamine CAS 920503-60-2 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

(E)-2-(9-Benzyl-9H-purin-6-yl)-N,N-diethylethenamine (CAS 920503-60-2) is a high-purity analytical reference standard with the molecular formula C18H21N5 and a molecular weight of 307.39 g/mol.

The molecular framework of (E)-2-(9-Benzyl-9H-purin-6-yl)-N,N-diethylethenamine (C18H21N5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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).

As a certified reference material (CRM), (E)-2-(9-Benzyl-9H-purin-6-yl)-N,N-diethylethenamine 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.
