The molecular framework of 1-(5-Chloro-2-methylphenyl)-N-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (C24H18ClN5O) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
1-(5-Chloro-2-methylphenyl)-N-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (CAS 890937-57-2), molecular formula C24H18ClN5O and molecular weight 427.89 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-(5-Chloro-2-methylphenyl)-N-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-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.
