4-(4-Ethyl-5-methyl-1H-pyrazol-3-yl)benzonitrile CAS 488114-78-9

Description

4-(4-Ethyl-5-methyl-1H-pyrazol-3-yl)benzonitrile (C13H13N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

4-(4-Ethyl-5-methyl-1H-pyrazol-3-yl)benzonitrile (CAS 488114-78-9), molecular formula C13H13N3 and molecular weight 211.26 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.
