Used as a chiral resolving agent in organic synthesis to separate enantiomers of basic compounds, particularly amines. Its ability to form diastereomeric salts with racemic mixtures allows for effective crystallization-based separation. Also serves as a catalyst or acid additive in asymmetric synthesis and pharmaceutical manufacturing. Commonly employed in the preparation of chiral intermediates for drugs and fine chemicals. Additionally, it finds use in electrochemical applications and as a dopant in conductive polymers due to its stability and solubility properties.
