Chemical Structure
Description
As a certified reference material (CRM), 9-Benzyl-2-chloro-N-(4-methoxyphenyl)-9H-purin-6-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.
9-Benzyl-2-chloro-N-(4-methoxyphenyl)-9H-purin-6-amine (CAS 125827-87-4) is a high-purity analytical reference standard with the molecular formula C22H22ClN5O and a molecular weight of 407.90 g/mol.
The molecular framework of 9-Benzyl-2-chloro-N-(4-methoxyphenyl)-9H-purin-6-amine (C22H22ClN5O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
