1-Allyl-3-Ethylimidazolium Bis((Trifluoromethyl)Sulfonyl)Imide works as an ionic liquid. It’s known by its molecular formula: C11H15F6N3O4S2. The chemical structure combines an imidazolium cation with a bis((trifluoromethyl)sulfonyl)imide anion. These molecules come together to create a material with a set of unique properties. Compared to standard organic solvents, this ionic liquid remains stable across a wider temperature range. Many research groups rely on this stability for experiments that push the limits of reactivity and selectivity, such as in electrochemistry, catalysis, advanced materials processing, and battery work.
The material looks different depending on temperature and storage conditions. It usually comes as a clear, colorless liquid at room temperature, but in cooler labs or during shipping, you might find it as a powder, set of flakes, or even waxy pearls. The melting point hovers below 20°C, so in most offices and factories, it flows as a liquid. Density remains a key spec—about 1.45 g/cm³ at 25°C. Solubility stands out as a highlight. It mixes well with other polar chemicals but shows a near total aversion to water, which enables selective chemistry. Many solvents evaporate or react during storage, but due to its ionic character, this material resists evaporation under normal atmospheric conditions. It doesn’t vaporize like water or acetone, making spills less likely to fill the air with fumes.
With the formula C11H15F6N3O4S2, each molecule carries a bulky sulfonyl imide group attached to a trifluoromethyl ring. The structure relies on a charged imidazolium ring, where the nitrogen atoms at positions 1 and 3 are bound to allyl and ethyl groups. This specific set-up gives the ionic liquid exceptional resistance to oxidation, reduction, and basic conditions. In practical terms, researchers can use this product in tough chemical environments—such as in lithium-ion battery electrolytes or during the synthesis of moisture-sensitive compounds. Its structure has a measurable effect on viscosity and ionic conductivity, making it a favorite for labs designing high-efficiency, next-generation devices.
Producers supply 1-Allyl-3-Ethylimidazolium Bis((Trifluoromethyl)Sulfonyl)Imide in different physical forms. Most users prefer the liquid, which pours easily and mixes without clumping. Some applications or shipping regulations require powder, flakes, pearls, or even pressed crystalline forms. Powder works in processes aiming for maximum surface area, while pearls resist caking and store well during transport. Occasionally, a crystalline sample comes in handy for precise weighing or spectroscopic analysis. The choice often falls to customer preference, storage space, or intended use, but the base chemical stays the same, no matter the form. A liter covers about 1.45 kg, so order quantities depend on project scale and container size.
This ionic liquid’s density sits above 1.4 g/cm³, outclassing most common solvents like ethanol or acetone. The molecular weight clocks in around 467 g/mol. Its low volatility and thermal stability make it a workhorse in situations where flammable liquids would only add hazards. In battery formulation, fuel cells, and innovative synthetic chemistry, these traits cut down on workplace risk. Its non-flammable character helps companies meet strict safety standards, which matters more as insurance rules tighten in both research and industry. Besides, it acts as an excellent raw material for making custom ionic liquids, which opens up options for tailored formulations and the development of new electrolytes or catalysts. Chemists value that versatility, especially for sustainable synthesis and recycling procedures where resource recovery matters more than ever.
Handling any chemical in this class comes with some responsibility. 1-Allyl-3-Ethylimidazolium Bis((Trifluoromethyl)Sulfonyl)Imide generally escapes the flammability and explosion risks attached to classic solvents, but it isn’t benign. Some evidence points toward moderate skin and eye irritation after direct contact. Inhalation of vapor isn’t a major risk, but ingestion or prolonged exposure raises safety questions we can’t ignore. It doesn’t break down rapidly in wastewater, so responsible disposal practices matter. Industry guidance points out the need to wear gloves, eye protection, and lab coats during handling. Spills must be contained and gathered for chemical waste treatment. Some labs run closed systems to recover and recycle excess, especially when cost or environmental restrictions apply. This approach keeps the substance out of ground and surface waters and cuts down on long-term risk for factory workers and communities nearby. Both regulators and responsible users recognize the necessity of sound chemical hygiene from warehouse to bench.
Customs and trade revolve around the Harmonized System (HS) for product classification. 1-Allyl-3-Ethylimidazolium Bis((Trifluoromethyl)Sulfonyl)Imide typically falls under HS Code 2933.39, identifying it among heterocyclic compounds with nitrogen only. Checking the latest trade rules and country-specific regulations reduces delays at international borders and avoids mislabeling fines. Given its pharmaceutical and specialty chemical uses, some shipments draw closer scrutiny—especially in regions tightening rules on high-purity raw materials. Manufacturers keep Material Safety Data Sheets (MSDS) on hand, not only to comply, but as a roadmap for safe transport, emergency response, and chemical inventory checks. The global community continues to review ionic liquids for potential impacts on health and the environment, so future rule changes can’t be ruled out. Keeping track of this paperwork remains part of the real cost of dealing in advanced chemical products like this one.
