5-Amino-1-(2,5-difluorophenyl)-3-methyl-1h-pyrazole-4-carbonitrile (CAS 1072944-86-5), molecular formula C11H8F2N4 and molecular weight 234.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Amino-1-(2,5-difluorophenyl)-3-methyl-1h-pyrazole-4-carbonitrile (C11H8F2N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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.
