1-Ethyl-3-methylimidazolium bis(pentafluoroethylsulfonyl)imide CAS 216299-76-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Ethyl-3-methylimidazolium bis(pentafluoroethylsulfonyl)imide.

CATO supplies 1-Ethyl-3-methylimidazolium bis(pentafluoroethylsulfonyl)imide (CAS 216299-76-2), a certified reference material (molecular formula C4F10NO4S2C6H11N2, MW 491.31 g/mol) for analytical method development and quality control.

1-Ethyl-3-methylimidazolium bis(pentafluoroethylsulfonyl)imide (C4F10NO4S2C6H11N2) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.

CATO manufactures 1-Ethyl-3-methylimidazolium bis(pentafluoroethylsulfonyl)imide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
