1-[3-(2-fluorophenyl)-1H-pyrazol-5-yl]piperazine (CAS 1542693-16-2) is a high-purity analytical reference standard with the molecular formula C13H15FN4 and a molecular weight of 246.28 g/mol.
The molecular framework of 1-[3-(2-fluorophenyl)-1H-pyrazol-5-yl]piperazine (C13H15FN4) 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. 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.
