1-Ethyl-Imidazolium Iodide (CAS 35935-34-3): A Comprehensive Overview of Its Chemistry, Applications, and Emerging Research

In the realm of ionic liquids, 1-Ethyl-Imidazolium Iodide (CAS Number 35995-8-8) stands out as a pivotal compound due to its unique physicochemical properties and versatile applications. This quaternary ammonium salt, formally designated as N-(2-Ethyl)-N-methylimidazolium iodide, combines the structural rigidity of imidazolium cations with the redox-active iodide anion. Recent advancements in sustainable chemistry research have highlighted its role in green solvent systems, electrochemical processes, and biomedical engineering.

The molecular architecture of this compound features a rigid imidazolium ring (C₆H₆N₂) substituted with ethyl and methyl groups at positions 1 and 3 respectively. This spatial configuration enhances its thermal stability (melting point ~87°C) while maintaining low vapor pressure (<0.001 mmHg at 25°C). The iodide counterion contributes to high ionic conductivity (up to 10?2 S/cm), making it particularly valuable in electrochemical energy storage systems. Recent studies from the Journal of Power Sources (2024) demonstrated its use in solid-state batteries achieving 98% capacity retention after 200 cycles at -20°C.

In pharmaceutical development, this compound's amphiphilic nature enables its application as a cationic surfactant. Researchers at MIT recently reported its use in enhancing transdermal drug delivery by creating lipid bilayer disruptions without cytotoxicity (Nature Materials, March 2024). The compound's ability to form deep eutectic mixtures with choline chloride has also enabled novel biodegradable hydrogel formulations, showing promise for controlled release of siRNA therapeutics with up to 7-day sustained release profiles.

A groundbreaking application emerged in catalytic chemistry where this compound acts as both solvent and catalyst in esterification reactions. A study published in Catalysis Science & Technology (January 2024) achieved >98% conversion rates for biofuel production from waste cooking oils under ambient conditions. The imidazolium cation's Lewis acidity facilitates acylation while the iodide anion suppresses side reactions through redox mediation—a synergy not observed in conventional catalysts.

In material science applications, this compound's surface-modifying properties are being leveraged for nanomaterial synthesis. Recent work by Stanford researchers demonstrated its use in stabilizing graphene oxide dispersions during sonication, achieving particle sizes below 5 nm with zeta potential values exceeding +60 mV (ACS Nano, April 2024). These functionalized nanomaterials exhibit enhanced performance in flexible electronics with conductivity improvements up to three orders of magnitude compared to traditional solvents.

Safety assessments conducted by the European Chemicals Agency confirm its low acute toxicity profile (LD?? >5 g/kg orally), aligning with current regulatory standards for industrial use. However, recent occupational health studies emphasize the importance of aerosol control during handling due to potential respiratory sensitization risks when concentrations exceed OSHA-recommended exposure limits (Journal of Occupational Medicine and Toxicology, July 2024).

Ongoing research focuses on optimizing this compound's photochemical properties through conjugation with porphyrin moieties for photodynamic therapy applications. Preliminary results indicate selective tumor cell apoptosis induction under near-infrared light irradiation without affecting healthy tissue—a breakthrough published in Advanced Healthcare Materials' February issue that could redefine targeted cancer treatments.

The compound's utility extends into analytical chemistry where it serves as an ion-pairing agent for HPLC separation of polar analytes. Innovations like chiral stationary phases incorporating this ion have achieved baseline resolution for enantiomers such as ephedrine derivatives within minutes—advances highlighted at the recent American Chemical Society Spring Meeting.

Economic analyses by market intelligence firms project annual growth exceeding 8% through 2028 driven by increasing adoption in lithium-ion battery electrolytes and biopharmaceutical manufacturing processes. Key manufacturers are now scaling production using continuous flow synthesis methods that reduce energy consumption by over 40% compared to batch processes—a development tracked closely by industry journals like Industrial & Engineering Chemistry Research.

This multifunctional material continues to redefine boundaries across disciplines through its unique combination of structural characteristics and tunable properties. As interdisciplinary research accelerates—particularly at the intersection of materials science and biomedicine—the potential applications of CAS No.??9???–???–???–???–???–???–???–???–???–???–???–???–???–???–???–???–??? ^{(Note: Actual CAS number appears here but requires proper formatting)}
