Chemical Structure
Description
The molecular framework of 9-Benzyl-6-(trifluoromethyl)-9H-purin-2-amine (C13H10F3N5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine 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).
9-Benzyl-6-(trifluoromethyl)-9H-purin-2-amine (CAS 1643-91-0), molecular formula C13H10F3N5 and molecular weight 293.25 g/mol, is a CATO reference standard with documented purity and traceability.
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), 9-Benzyl-6-(trifluoromethyl)-9H-purin-2-amine 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.
