Chemical Structure

5-Amino-1-(5-chloro-2-methylphenyl)-3-methyl-1H-pyrazole-4-carbonitrile CAS 2197063-33-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Amino-1-(5-chloro-2-methylphenyl)-3-methyl-1H-pyrazole-4-carbonitrile.

CATO supplies 5-Amino-1-(5-chloro-2-methylphenyl)-3-methyl-1H-pyrazole-4-carbonitrile (CAS 2197063-33-3), a certified reference material (molecular formula C12H11ClN4, MW 246.70 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 5-Amino-1-(5-chloro-2-methylphenyl)-3-methyl-1H-pyrazole-4-carbonitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 246.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
