Chemical Structure
Description
4-(2-Aminoethyl)-3-(4-fluorophenyl)-1H-pyrazol-5-ol (CAS 878208-78-7) is a high-purity analytical reference standard with the molecular formula C11H12FN3O and a molecular weight of 221.23 g/mol.
Based on its molecular formula C11H12FN3O, 4-(2-Aminoethyl)-3-(4-fluorophenyl)-1H-pyrazol-5-ol contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 221.23 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.
