Chemical Structure
Description
The occurrence of 1-Ethyl-3-methyl-1h-imidazol-3-ium dibutyl phosphate is closely related to an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Ethyl-3-methyl-1h-imidazol-3-ium dibutyl phosphate (CAS 869858-84-4) is a high-purity analytical reference standard with the molecular formula C8H18O4PC6H11N2 and a molecular weight of 320.37 g/mol.
The molecular framework of 1-Ethyl-3-methyl-1h-imidazol-3-ium dibutyl phosphate (C8H18O4PC6H11N2) is characterized by an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
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), 1-Ethyl-3-methyl-1h-imidazol-3-ium dibutyl phosphate 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.
