3-Dodecyl-1,2-dimethyl-1H-imidazol-3-ium bromide CAS 61546-10-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Dodecyl-1,2-dimethyl-1H-imidazol-3-ium bromide.

3-Dodecyl-1,2-dimethyl-1H-imidazol-3-ium bromide (CAS 61546-10-9), molecular formula C17H35N2Br and molecular weight 347.38 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C17H35N2Br, 3-Dodecyl-1,2-dimethyl-1H-imidazol-3-ium bromide contains bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 347.38 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.

As a certified reference material (CRM), 3-Dodecyl-1,2-dimethyl-1H-imidazol-3-ium 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.
