Description

Benzyltriethylammonium chloride (CAS No. 56-37-1), also known as TEBAC, is a quaternary ammonium salt with the molecular formula C₁₃H₂₂ClN. This high-purity compound is widely used as a phase-transfer catalyst (PTC) in organic synthesis due to its ability to facilitate reactions between immiscible phases. It is particularly effective in nucleophilic substitution, esterification, and polymerization reactions. The product is supplied as a white crystalline powder with excellent solubility in polar solvents such as water, methanol, and ethanol. Suitable for laboratory and industrial applications, it is rigorously tested to ensure consistency, stability, and optimal catalytic performance. Store in a cool, dry place away from incompatible materials.
