Chemical Structure
Description
As a certified reference material (CRM), 4-Chloro-7-phenyl-5H-pyrrolo[3,2-d]pyrimidine 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.
4-Chloro-7-phenyl-5H-pyrrolo[3,2-d]pyrimidine (CAS 201465-28-3) is a high-purity analytical reference standard with the molecular formula C12H8ClN3 and a molecular weight of 229.67 g/mol.
The molecular framework of 4-Chloro-7-phenyl-5H-pyrrolo[3,2-d]pyrimidine (C12H8ClN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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.
