2-[4-(4-Fluorophenyl)piperazin-1-yl]quinoxaline CAS 339104-74-4

Description

Compared with other compounds in its class, the molecular weight of 308.35 g/mol gives 2-[4-(4-Fluorophenyl)piperazin-1-yl]quinoxaline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-[4-(4-Fluorophenyl)piperazin-1-yl]quinoxaline (CAS 339104-74-4), a certified reference material (molecular formula C18H17FN4, MW 308.35 g/mol) for analytical method development and quality control.

2-[4-(4-Fluorophenyl)piperazin-1-yl]quinoxaline (C18H17FN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
