dodecyl(2-hydroxyethyl)dimethylazanium bromide CAS 7009-61-2

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.

dodecyl(2-hydroxyethyl)dimethylazanium bromide (CAS 7009-61-2), molecular formula C16H36NOBr and molecular weight 338.37 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C16H36NOBr, dodecyl(2-hydroxyethyl)dimethylazanium bromide contains an amide 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 338.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
