Description

2-Henicosyl-4,5-Dihydro-1-(2-Hydroxyethyl)-3-Methyl-1H-Imidazolium Methyl Sulphate is a high-purity, long-chain imidazolium-based ionic liquid with unique surfactant and phase-transfer properties. This compound is valued for its ability to act as a highly effective cationic surfactant and catalyst in specialized organic synthesis and material science applications. It is primarily sought by R&D and production teams in the specialty chemicals, advanced materials, and pharmaceutical intermediates sectors for developing novel formulations and processes.

Application

• Phase-Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases, particularly useful in alkylation and polymerization processes.
• Specialty Surfactant: Serves as a cationic surfactant in the formulation of high-performance fabric softeners, hair conditioners, and antistatic agents.
• Ionic Liquid Solvent/Medium: Used as a green, non-volatile reaction medium for organic synthesis, electrochemistry, and separation technologies.
• Pharmaceutical Intermediate: Employed in the synthesis of complex drug molecules and active pharmaceutical ingredients (APIs) requiring specific cationic functionalities.
• Corrosion Inhibitor: Acts as an additive in industrial fluids and coatings to protect metal surfaces.
• Nanomaterial Synthesis: Functions as a templating agent or stabilizer in the production of nanoparticles and advanced porous materials.
• Textile Auxiliary: Used in dyeing and finishing processes to improve dye uptake and fabric handle.

Quality Control

Our 2-Henicosyl-4,5-Dihydro-1-(2-Hydroxyethyl)-3-Methyl-1H-Imidazolium Methyl Sulphate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and consistent high-grade quality. Certificates of Analysis (COA) detailing all relevant parameters are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality and stability. Keep away from incompatible materials.
