Description

Compared with other compounds in its class, the molecular weight of 246.70 g/mol gives 5-AMino-1-(4-chloro-3-methyl-phenyl)-3-methyl-1h-pyrazole-4-carbonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-AMino-1-(4-chloro-3-methyl-phenyl)-3-methyl-1h-pyrazole-4-carbonitrile (CAS 2173090-23-6) is a high-purity analytical reference standard with the molecular formula C12H11ClN4 and a molecular weight of 246.70 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 5-AMino-1-(4-chloro-3-methyl-phenyl)-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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
