1031605-58-9 2-Phenyl-2,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-one MFCD14281722 (CAS 1031605-58-9), molecular formula C11H8N4O and molecular weight 212.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1031605-58-9 2-Phenyl-2,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-one MFCD14281722 (C11H8N4O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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).
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), 1031605-58-9 2-Phenyl-2,5-dihydro-4H-pyrazolo[3,4-d]pyrimidin-4-one MFCD14281722 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.
