Chemical Structure

<I>p</I>-Xylene-bis(N-pyridinium bromide) CAS 14208-10-7 chemical structure

Description

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.

<I>p</I>-Xylene-bis(N-pyridinium bromide) (CAS 14208-10-7) is a high-purity analytical reference standard with the molecular formula C18H34N2Br and a molecular weight of 358.39 g/mol.

Structurally, <I>p</I>-Xylene-bis(N-pyridinium bromide) (C18H34N2Br) contains a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 358.39 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
