5-Amino-1-(4-chloro-2-methylphenyl)-1H-pyrazole-4-carbonitrile CAS 58791-80-3

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 5-Amino-1-(4-chloro-2-methylphenyl)-1H-pyrazole-4-carbonitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 232.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

5-Amino-1-(4-chloro-2-methylphenyl)-1H-pyrazole-4-carbonitrile (CAS 58791-80-3), molecular formula C11H9ClN4 and molecular weight 232.67 g/mol, is a CATO reference standard with documented purity and traceability.

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.

As a certified reference material (CRM), 5-Amino-1-(4-chloro-2-methylphenyl)-1H-pyrazole-4-carbonitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
