1-(2-Hydroxyethyl)-3-methylimidazolium dicyanamide
1-(2-Hydroxyethyl)-3-methylimidazolium dicyanamide (CAS 1186103-47-8; C8H11N5O; molar mass 193.21 g/mol) is a hydroxyl-functionalised imidazolium dicyanamide ionic liquid, abbreviated [C2OHMIM][DCA]. It pairs a 2-hydroxyethyl-substituted methylimidazolium cation with a dicyanamide anion, giving a low-melting, low-volatility salt used as a designer solvent and reaction medium in chemical synthesis and specialty research. Tech Serve Solutions supplies it at ≥96.5% (HPLC) assay for laboratory and process applications.

Designer solvent and reaction medium
As a room-temperature ionic liquid, [C2OHMIM][DCA] serves as a non-volatile, thermally stable solvent for organic synthesis and catalysis. Its negligible vapour pressure makes it a practical alternative to conventional volatile organic solvents in research settings.
Functionalised (task-specific) ionic liquid
The pendant 2-hydroxyethyl group provides a reactive hydroxyl handle and added hydrogen-bonding capacity. This task-specific functionality is widely exploited when tuning solvation, polarity and interactions with substrates or catalysts.
Dicyanamide-anion media
Dicyanamide-based ionic liquids are valued for relatively low viscosity and good solubilising power toward a broad range of organic and inorganic species. The anion supports use as a coordinating, designer reaction medium.
Electrochemistry and materials research
Imidazolium ionic liquids of this type are commonly studied as electrolytes and as media in materials and surface research. Use here is general and depends on the specific experimental system.
Chemical and specialty synthesis
The compound is supplied for chemical synthesis and specialty synthesis programmes, where it functions as a reagent-grade ionic liquid building block and solvent for method development.
