Chemical Structure
Description
The occurrence of N,N-Diethyl-N-methylethanaminium bromide is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N,N-Diethyl-N-methylethanaminium bromide (CAS 2700-16-5), molecular formula C7H18NBr and molecular weight 196.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N,N-Diethyl-N-methylethanaminium bromide (C7H18NBr) is characterized by bromine 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. 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.
As a certified reference material (CRM), N,N-Diethyl-N-methylethanaminium bromide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
