3h-Pyrazolo[3,4-c]pyridine CAS 271-46-5

Description

Compared with other compounds in its class, the molecular weight of 119.12 g/mol gives 3h-Pyrazolo[3,4-c]pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3h-Pyrazolo[3,4-c]pyridine (CAS 271-46-5) is a high-purity analytical reference standard with the molecular formula C6H5N3 and a molecular weight of 119.12 g/mol.

Based on its molecular formula C6H5N3, 3h-Pyrazolo[3,4-c]pyridine contains a nitrile group, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 119.12 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.
