2-[4-(3,4-Dichlorophenyl)piperazin-1-yl]quinoxaline CAS 339105-74-7

Description

The occurrence of 2-[4-(3,4-Dichlorophenyl)piperazin-1-yl]quinoxaline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-[4-(3,4-Dichlorophenyl)piperazin-1-yl]quinoxaline (CAS 339105-74-7) is a high-purity analytical reference standard with the molecular formula C18H16Cl2N4 and a molecular weight of 359.25 g/mol.

2-[4-(3,4-Dichlorophenyl)piperazin-1-yl]quinoxaline (C18H16Cl2N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
