4-Hydrazinyl-1-methyl-1H-pyrazolo[3,4-d]pyrimidine (CAS 5334-72-5), molecular formula C6H8N6 and molecular weight 164.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Hydrazinyl-1-methyl-1H-pyrazolo[3,4-d]pyrimidine (C6H8N6) is characterized by a nitrile group, an aromatic ring system. 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 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).
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.
