1H-Pyrazolo[3,4-b]pyridin-4-ylhydrazine CAS 49834-59-5

Description

The occurrence of 1H-Pyrazolo[3,4-b]pyridin-4-ylhydrazine is closely related to a nitrile group, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1H-Pyrazolo[3,4-b]pyridin-4-ylhydrazine (CAS 49834-59-5), molecular formula C6H7N5 and molecular weight 149.15 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C6H7N5, 1H-Pyrazolo[3,4-b]pyridin-4-ylhydrazine contains a nitrile group, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 149.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
