1-(3,4-Difluorobenzoyl)piperazine hydrochloride CAS 1171078-91-3

Description

The occurrence of 1-(3,4-Difluorobenzoyl)piperazine hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(3,4-Difluorobenzoyl)piperazine hydrochloride (CAS 1171078-91-3), molecular formula C11H12F2N2OHCl and molecular weight 262.68 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H12F2N2OHCl, 1-(3,4-Difluorobenzoyl)piperazine hydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 262.68 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
