2-(4-amino-1H-pyrazol-1-yl)pyridine-3-carbonitrile hydrochloride CAS 1461707-43-6

Description

2-(4-amino-1H-pyrazol-1-yl)pyridine-3-carbonitrile hydrochloride (CAS 1461707-43-6) is a high-purity analytical reference standard with the molecular formula C9H7N5HCl and a molecular weight of 221.65 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 2-(4-amino-1H-pyrazol-1-yl)pyridine-3-carbonitrile hydrochloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 221.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
