Chemical Structure
Description
As a certified reference material (CRM), 7-Phenyl-7H-purine 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.
7-Phenyl-7H-purine (CAS 18346-05-9) is a high-purity analytical reference standard with the molecular formula C11H8N4 and a molecular weight of 196.21 g/mol.
The molecular framework of 7-Phenyl-7H-purine (C11H8N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
