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.
1,1'-(Dodecane-1,12-diyl)bis(3-methylpyridin-1-ium) bromide (CAS 525596-66-1) is a high-purity analytical reference standard with the molecular formula C24H38N2Br and a molecular weight of 434.49 g/mol.
Structurally, 1,1'-(Dodecane-1,12-diyl)bis(3-methylpyridin-1-ium) bromide (C24H38N2Br) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.5, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 434.49 g/mol, it falls into the moderately-high-molecular-weight range. 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.
