1-Decyl-2-methylimidazole, CAS: 42032-30-4

Key Applications:

1. Precursor and Building Block for Ionic Liquids

• Serves as an alkylated imidazole scaffold for synthesizing hydrophobic ionic liquids through quaternization with alkyl halides or functional electrophiles.
• Enables the preparation of long‑chain imidazolium salts with tunable viscosity, polarity, and interfacial behavior for electrochemical and separation applications.

2. Surfactants and Amphiphilic Additives

• The C10 alkyl chain imparts strong amphiphilicity, making it suitable as a precursor for cationic surfactants.
• Useful in formulations requiring controlled micelle formation, wetting, or dispersion in non‑aqueous or mixed‑solvent systems.

3. Phase‑Transfer and Catalytic Ligand Applications

• Acts as a nucleophilic base or ligand in organic synthesis, particularly in alkylation, condensation, and heterocycle‑forming reactions.
• Long‑chain substitution enhances solubility in organic media, supporting phase‑transfer catalysis in biphasic systems.

4. Corrosion Inhibition Research

• Imidazole derivatives with hydrophobic tails are widely studied as corrosion inhibitors for steel, copper, and aluminum alloys.
• The decyl chain promotes adsorption onto metal surfaces, forming protective hydrophobic films in acidic or saline environments.

5. Materials and Polymer Additives

• Can be incorporated into polymer matrices or coatings to introduce ionic character, improve adhesion, or modify surface energy.
• Useful in designing antistatic materials, ion‑conductive composites, and functional coatings.

6. Solvent and Extraction System Modifier

• Enhances solubility of hydrophobic analytes when used as an additive in extraction systems.
• Supports the formation of task‑specific ionic liquids for metal ion extraction, biomass fractionation, or organic separations.

7. Antimicrobial and Bioactive Molecule Development

• Imidazole derivatives with long alkyl chains are investigated for antimicrobial, antifungal, and membrane‑active properties.
• Suitable as a structural motif in early‑stage medicinal chemistry or materials with antimicrobial surfaces.
