Used as a chiral resolving agent in organic synthesis, particularly for the separation of enantiomers of basic compounds. Its sulfonic acid group provides strong acidity and good solubility in polar solvents, while the bulky camphor backbone ensures high stereoselectivity. Commonly employed in the resolution of amines, amino alcohols, and other chiral bases through diastereomeric salt formation. The ammonium salt form enhances stability and crystallinity, facilitating isolation and purification. Also utilized in asymmetric synthesis and as a chiral auxiliary in pharmaceutical development.
