Triethyl Benzyl Ammonium Chloride (TEBAC) is a quaternary ammonium salt commonly used as a phase-transfer catalyst and antimicrobial agent.

Chemical description

Chemical name: Benzyltriethylammonium chloride

Molecular formula: C₁₃H₂₂ClN

Molecular weight: ~227.77 g/mol

Structure: A positively charged quaternary ammonium ion with one benzyl group and three ethyl groups, paired with a chloride anion.

Key uses

Phase-transfer catalyst (PTC): Facilitates reactions between water-soluble and organic-soluble reactants in organic synthesis

Chemical intermediate: Used in pharmaceuticals, agrochemicals, and specialty chemicals

Antimicrobial / disinfectant formulations: Due to quaternary ammonium activity (limited compared to longer-chain quats)
