Used as a chiral resolving agent in organic synthesis, particularly for the separation of enantiomers in pharmaceutical intermediates. Its quaternary ammonium structure enhances solubility and stability in aqueous and polar organic solvents, making it suitable for ion-exchange chromatography. Also employed as a catalyst phase-transfer agent in asymmetric synthesis, where the chlorine and hydroxyl groups contribute to substrate coordination and stereocontrol. Additionally, it serves as a building block in the preparation of bioactive molecules and ionic liquids with tailored chirality for use in enantioselective reactions.
