Description

1-(3,4-Difluorophenyl)-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one (CAS 1082528-72-0), molecular formula C11H6F2N4O and molecular weight 248.19 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-(3,4-Difluorophenyl)-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one (C11H6F2N4O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 248.19 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 1-(3,4-Difluorophenyl)-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-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.
