4-Cyclopropyl-1-phenyl-1,6-dihydro-7H-pyrazolo[3,4-d]pyridazin-7-one CAS 1105197-41-8

Description

4-Cyclopropyl-1-phenyl-1,6-dihydro-7H-pyrazolo[3,4-d]pyridazin-7-one (CAS 1105197-41-8), molecular formula C14H12N4O and molecular weight 252.27 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-Cyclopropyl-1-phenyl-1,6-dihydro-7H-pyrazolo[3,4-d]pyridazin-7-one (C14H12N4O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 252.27 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
