1-Octyl-2,3-Dimethylimidazolium Bis((Trifluoromethyl)Sulfonyl)Imide stands out as a distinct ionic liquid, securing a place in modern material science laboratories. This substance features the molecular formula C18H28F6N2O4S2 and a molecular weight of 548.55 g/mol. The imidazolium ring, combined with two methyl groups and an octyl chain, offers chemical properties suited for processes needing low volatility and high thermal stability. In research and industrial environments, interest often revolves around its specific structure: an imidazolium cation matched with a bis((trifluoromethyl)sulfonyl)imide anion, leading to a robust, stable, and flexible compound fit for challenging environments.
Product form varies; users may encounter this substance as clear to yellow liquids, pearlescent beads, white or off-white solid flakes, or as fine crystalline powders. The crystalline form usually has a melting point between 40°C and 60°C, reflecting structural stability. The density hovers near 1.36-1.39 g/cm³ at room temperature, which places it between traditional solvents and heavier salts, making it easy to handle and store in the lab. Surface tension and viscosity differences also mark it as a standout for applications needing precise solubility or phase-transfer capabilities. For those using solutions, its solubility in polar organic solvents and partial miscibility in water enable more versatility in chemical synthesis, electrochemistry, and extraction. Raw materials for this chemical stem from imidazole derivatives, haloalkanes, and trifluoromethanesulfonyl-containing reagents, demanding precision in both synthesis and purification to guarantee quality and performance.
The molecular backbone centers on a 2,3-dimethylimidazolium ring, further tailored by an octyl group which lends hydrophobicity and surface activity. The pairing with bis((trifluoromethyl)sulfonyl)imide strengthens its resilience against hydrolysis and oxidative decomposition. The molecular design leads to a reduction in lattice energy, helping the compound remain as a liquid across a broader temperature span. This thermal and chemical resilience makes the product an attractive choice as a solvent in high-temperature reactions, additives in electroplating baths, or as a non-volatile medium in catalysis research. Compared to conventional salts, these ionic liquids create less vapor and reduce atmospheric contamination in the workspace.
Handling chemicals with fluorinated sulfonyl components demands attention because of potential toxicity and reactivity under strong acidic or oxidative environments. 1-Octyl-2,3-Dimethylimidazolium Bis((Trifluoromethyl)Sulfonyl)Imide is not exempt—prolonged exposure to skin or eyes leads to irritation, while vapor inhalation in confined spaces stirs breathing difficulties or headaches, based on safety reports and direct experience in research settings. Suitable gloves, protective glasses, and local extraction systems cut the risk dramatically. This compound falls under HS Code 2933.19, placing it within heterocyclic organic intermediates which require clear labeling and careful storage. Industrial protocols stress the importance of spill management with neutral absorbents and the use of dedicated, sealed containers to minimize accidental releases. Disposal requires channeling waste solutions to certified handlers, avoiding casual disposal that could pollute water supplies.
Many labs trust this ionic liquid when synthesizing specialty chemicals, crafting batteries, or mediating phase-transfer reactions. Electrochemically, its low volatility and high conductivity make it a top pick for electrolyte research and high-performance lithium batteries. Large-scale industrial users value the dependably wide liquid range, letting processes run hotter or colder with less concern for evaporation or decomposition. My own work with this compound during extractions and metal recovery demonstrates not only high selectivity but also resource efficiency; using less solvent for equivalent yields. Once a niche laboratory material, its broader reach now includes devices, organic synthesis, and even specialty coatings or lubricants.
Raw materials containing fluorinated groups create waste streams that pose disposal challenges. Waste minimization begins with process design—closed-loop recycling systems conserve both solvent and resources, reducing new material needs. Regulations increasingly require data on persistence in the environment, as fluorinated organic molecules don’t break down quickly. Responsible suppliers and labs must partner to maintain careful documentation, risk assessments, and staff training. In situations of accidental exposure, quick access to eyewash stations and chemical showers cuts down on harm. Shifting toward greener synthesis pathways, employing renewable feedstocks or greener anion alternatives could reduce overall hazard, though any substitution must account for performance in end applications.
1-Octyl-2,3-Dimethylimidazolium Bis((Trifluoromethyl)Sulfonyl)Imide, under HS Code 2933.19, shows up in laboratories and factories as a solid, powder, pearl, or liquid—sometimes crystalline, each with specific density and melting points. Its molecular properties make it a superior solvent for many advanced applications, but responsible use and disposal are not optional. Anyone handling raw materials or formulated products faces a clear duty to manage risk effectively. Training, engineering controls, and recycling programs lower the hazard without sacrificing productivity. While no chemical comes without risk, understanding the full properties—density, structure, reactivity, and safe handling—means getting the most benefit for least harm.
