Description

Emim Oh is a high-purity ionic liquid, specifically the hydroxide salt of the 1-ethyl-3-methylimidazolium cation. This compound serves as a powerful, non-aqueous organic base and a versatile precursor for synthesizing other ionic liquids. It is essential for advanced applications requiring moisture-controlled environments and high reactivity. Key industries utilizing this material include pharmaceuticals, organic synthesis, and materials science for catalysis and electrolyte formulation.

Application

• As a non-aqueous, strong base catalyst in organic synthesis reactions, such as condensations and deprotonations.
• Precursor for the synthesis of other 1-ethyl-3-methylimidazolium (EMIM) based ionic liquids via anion metathesis.
• Component in electrolyte formulations for advanced electrochemical devices, including batteries and capacitors.
• Use in pharmaceutical intermediate manufacturing where controlled basicity is required.
• Catalyst or co-catalyst in polymerization and materials synthesis processes.
• Research and development of green chemistry applications and novel solvent systems.

Quality Control

Our Emim Oh is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards for research and industrial use. Certificates of Analysis (COA) with detailed chromatographic and spectroscopic data are provided to guarantee batch-to-batch consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Recommended long-term storage temperature is 2-8°C.
