Chemical Structure

1-(4-Bromo-2-fluorophenyl)piperazine CAS 501903-57-7 chemical structure

Description

The occurrence of 1-(4-Bromo-2-fluorophenyl)piperazine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-(4-Bromo-2-fluorophenyl)piperazine (CAS 501903-57-7), a certified reference material (molecular formula C10H12BrFN2, MW 259.12 g/mol) for analytical method development and quality control.

1-(4-Bromo-2-fluorophenyl)piperazine (C10H12BrFN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine 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.
