Chemical Structure
Description
CATO supplies 2-((3-Chlorophenyl)amino)-1H-purin-6(9H)-one (CAS 123994-67-2), a certified reference material (molecular formula C11H8ClN5O, MW 261.67 g/mol) for analytical method development and quality control.
The molecular framework of 2-((3-Chlorophenyl)amino)-1H-purin-6(9H)-one (C11H8ClN5O) is characterized by a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), 2-((3-Chlorophenyl)amino)-1H-purin-6(9H)-one 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.
