5-Amino-1-(4-methylphenyl)-1H-pyrazole-4-carbonitrile CAS 103646-82-8

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 5-Amino-1-(4-methylphenyl)-1H-pyrazole-4-carbonitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 198.22 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).

CATO supplies 5-Amino-1-(4-methylphenyl)-1H-pyrazole-4-carbonitrile (CAS 103646-82-8), a certified reference material (molecular formula C11H10N4, MW 198.22 g/mol) for analytical method development and quality control.

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.
