Chemical Structure
Description
The occurrence of Piperidinium bromide is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Piperidinium bromide (CAS 14066-85-4) is a high-purity analytical reference standard with the molecular formula C5H11NHBr and a molecular weight of 166.06 g/mol.
The molecular framework of Piperidinium bromide (C5H11NHBr) is characterized by 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
