N-(2-Ethoxy-2-oxoethyl)-N,N-dimethyldodecan-1-aminium bromide CAS 1794-75-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(2-Ethoxy-2-oxoethyl)-N,N-dimethyldodecan-1-aminium bromide.

N-(2-Ethoxy-2-oxoethyl)-N,N-dimethyldodecan-1-aminium bromide (CAS 1794-75-8), molecular formula C18H38NO2Br and molecular weight 380.41 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C18H38NO2Br, N-(2-Ethoxy-2-oxoethyl)-N,N-dimethyldodecan-1-aminium bromide contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 380.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
