Chemical Structure
Description
2-(7H-Purin-6-yl)guanidine (CAS 446839-81-2), molecular formula C6H7N7 and molecular weight 177.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(7H-Purin-6-yl)guanidine (C6H7N7) is characterized by a nitrile group, an aromatic ring system. 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).
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), 2-(7H-Purin-6-yl)guanidine 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.
