3-(4-Bromophenyl)-1-(2-cyanoethyl)-1H-pyrazole-4-carbonitrile CAS 475626-49-4

Description

The occurrence of 3-(4-Bromophenyl)-1-(2-cyanoethyl)-1H-pyrazole-4-carbonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(4-Bromophenyl)-1-(2-cyanoethyl)-1H-pyrazole-4-carbonitrile (CAS 475626-49-4), molecular formula C13H9BrN4 and molecular weight 301.14 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C13H9BrN4, 3-(4-Bromophenyl)-1-(2-cyanoethyl)-1H-pyrazole-4-carbonitrile contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 301.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), 3-(4-Bromophenyl)-1-(2-cyanoethyl)-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.
