1-Ethoxyethyl-3-Methylimidazolium Tetrafluoroborate: Properties, Safety, and Practical Details

What is 1-Ethoxyethyl-3-Methylimidazolium Tetrafluoroborate?

1-Ethoxyethyl-3-Methylimidazolium Tetrafluoroborate stands as a member of the growing class of ionic liquids shaping sustainable trends in chemistry. Its molecular formula, C9H17BF4N2O, contains a 1-ethoxyethyl-3-methylimidazolium cation paired with a BF4– anion. HS Code classification usually points to 2933.99, which fits organic compounds with heterocyclic structures and boron content. Many years in a lab have shown ionic liquids like this one bringing both flexibility and new risk to synthesis, extraction, and energy storage work.

Physical Characteristics and Form

Anyone handling 1-ethoxyethyl-3-methylimidazolium tetrafluoroborate will notice its unique set of physical traits. Its appearance can shift between powder, pearls, or viscous liquid, sometimes presenting as flakes or even colorless to light yellow crystals depending on purity and conditions. Density generally lands close to 1.23 g/mL. The melting point tends to settle around 30°C, so what you see in the bottle can depend on storage temperatures. Solutions in a laboratory flask often remain clear, and it dissolves readily in polar solvents like water and acetonitrile. The ionic nature means low volatility, so fumes are less concerning than with solvents like ether or acetone.

Chemical Structure and Molecular Details

With experience handling many imidazolium-based compounds, the structure matters not only for reactivity but also for workplace safety measures. The imidazolium ring at its core interacts with the tetrafluoroborate through ionic attraction. This structure creates unique solvation effects. The tetrafluoroborate anion brings both chemical stability and a layer of complexity to waste disposal. When reviewing literature, degradation products and compatibility with metals or strong bases demand steady attention. The molecular property profile sets this compound apart for electrochemical or solvent applications. The BF4– lends stability across a broad pH range, but exposure to high temperatures can risk slow hydrolysis, potentially giving off small amounts of hydrogen fluoride.

Solubility, Solution, and Laboratory Use

Decades in the field show 1-ethoxyethyl-3-methylimidazolium tetrafluoroborate offering value as a solvent, supporting electrolyte, or in catalysis. Its high solubility in water and polar organics fits it to extraction tasks or as a matrix for metal ion transport. Much of its success comes from low vapor pressure and negligible flammability compared to traditional solvents. By using it as a material for batteries or fuel cells, teams unlock both thermal stability and wide voltage windows.

Safety, Hazard, and Environmental Impact

Chemical exposure stories tend to find their culprit in overlooked details. This ionic liquid should never be underestimated. Tetrafluoroborate-based salts can become harmful under misuse. Direct skin or eye contact may trigger irritation, sometimes leading to more serious issues after repeated exposure. Spills clean up with more effort than volatile liquids since the residue can persist, affecting surfaces and equipment. After years working with raw materials like this, I encourage the use of nitrile gloves, chemical splash goggles, and well-ventilated fume hoods at all stages, even if published data suggests low acute toxicity. Disposal brings another challenge: hydrolysis risk means wash-down with strong acids creates harmful boron and fluoride waste. Always route material through licensed chemical waste handlers, steering clear of ordinary drainage.

Specification and Sourcing

Detailed specifications become essential when ordering 1-ethoxyethyl-3-methylimidazolium tetrafluoroborate for research or industry. Most suppliers provide the compound in bottles of 25g up to several kilograms, described as powder, pearls, or viscous liquid. The average purity runs above 98%. Any additional water content and the presence of residual organics or hydrolysis products affect how well the compound performs in sensitive electronic or catalytic applications. Technical data sheets should show CAS number, exact molecular formula, density, and melting point. Product certificates from trusted sources can make a difference not only in regulatory audits but in real-world process outcomes.

Applications, Raw Materials, and Industry Importance

Everyone from green chemistry labs to electronics manufacturers pays attention to the evolution of ionic liquids. 1-ethoxyethyl-3-methylimidazolium tetrafluoroborate acts both as a raw material for advanced synthesis and as a process aid. Its use in lithium batteries and as a catalyst or medium for organometallic reactions shows ongoing relevance. Many teams now substitute it for classic solvents, aiming to lower workplace hazards and cut down on atmospheric emissions. Tetrafluoroborate chemistries, though, require checks and responsible protocols to offset chemical persistence in the environment and maintain safety for staff.

Improving Safe Handling and Reducing Hazards

Safer science comes from more than labels and locked cabinets. Training, documentation, and review cycles matter just as much as gloves and goggles. For those overseeing research or facility operations, every new raw material like 1-ethoxyethyl-3-methylimidazolium tetrafluoroborate earns a place in risk assessments, inventory audits, and spill response plans. Substitution for less hazardous materials can sometimes fit the task, but nothing beats robust communication about hazards, molecular properties, and possible reactions. Care with tetrafluoroborate wastes and process off-gassing keeps both people and ecosystems safer, and experience shows that even one overlooked material can threaten years of steady work.
