1,1,4,4-Tetramethylpiperazine-1,4-diium bromide CAS 24996-75-6

Description

Compared with other compounds in its class, the molecular weight of 224.17 g/mol gives 1,1,4,4-Tetramethylpiperazine-1,4-diium bromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,1,4,4-Tetramethylpiperazine-1,4-diium bromide (CAS 24996-75-6), molecular formula C8H20N2Br and molecular weight 224.17 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,1,4,4-Tetramethylpiperazine-1,4-diium bromide (C8H20N2Br) 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.
