Chemical Structure
Description
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.
CATO supplies N~5~-(2,4-dichlorophenyl)-5H-pyrazolo[3,4-d]pyrimidine-4,5-diamine (CAS 338403-46-6), a certified reference material (molecular formula C11H8Cl2N6, MW 295.13 g/mol) for analytical method development and quality control.
The molecular framework of N~5~-(2,4-dichlorophenyl)-5H-pyrazolo[3,4-d]pyrimidine-4,5-diamine (C11H8Cl2N6) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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.
As a certified reference material (CRM), N~5~-(2,4-dichlorophenyl)-5H-pyrazolo[3,4-d]pyrimidine-4,5-diamine 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.
