Chemical Structure
Description
The molecular framework of 2,2'-(Octanedioylbis(oxy))bis(N,N,N-trimethylethan-1-aminium) (C18H38N2O4I) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine 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.
2,2'-(Octanedioylbis(oxy))bis(N,N,N-trimethylethan-1-aminium) (CAS 7262-79-5), molecular formula C18H38N2O4I and molecular weight 473.41 g/mol, is a CATO reference standard with documented purity and traceability.
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.
