3,5-Di(2-pyridyl)pyrazole (CAS 129485-83-2) is a high-purity analytical reference standard with the molecular formula C13H10N4 and a molecular weight of 222.25 g/mol.
3,5-Di(2-pyridyl)pyrazole (C13H10N4) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
