Used in pharmaceutical research as a chiral resolving agent due to its ability to form stable diastereomeric complexes with racemic mixtures. Its structural rigidity and multiple hydrogen bonding sites make it effective in separating enantiomers of biologically active compounds, particularly in the purification of alkaloids and other nitrogen-containing heterocycles. Also employed in asymmetric synthesis where stereochemical control is critical. Its application extends to analytical chemistry for chiral stationary phases in HPLC when immobilized on silica supports.
