Description
As a certified reference material (CRM), 1-ethyl-3-methylimidazolium diethylphosphate 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.
1-ethyl-3-methylimidazolium diethylphosphate (CAS 848641-69-0) is a high-purity analytical reference standard with the molecular formula C4H10O4PC6H11N2 and a molecular weight of 264.26 g/mol.
1-ethyl-3-methylimidazolium diethylphosphate (C4H10O4PC6H11N2) contains an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
