1-(2-Bromo-4-nitrobenzyl)piperazine CAS 1183272-08-3

Description

Compared with other compounds in its class, the molecular weight of 300.15 g/mol gives 1-(2-Bromo-4-nitrobenzyl)piperazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(2-Bromo-4-nitrobenzyl)piperazine (CAS 1183272-08-3), molecular formula C11H14BrN3O2 and molecular weight 300.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-(2-Bromo-4-nitrobenzyl)piperazine (C11H14BrN3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
