Chemical Structure

5-Amino-4-(benzylamino)-1H-pyrazole-3-carbonitrile CAS 879223-59-3 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 5-Amino-4-(benzylamino)-1H-pyrazole-3-carbonitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 213.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

5-Amino-4-(benzylamino)-1H-pyrazole-3-carbonitrile (CAS 879223-59-3) is a high-purity analytical reference standard with the molecular formula C11H11N5 and a molecular weight of 213.24 g/mol.

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.
