Used as a chiral derivatizing agent in the resolution of enantiomers, particularly in the separation of racemic mixtures of carboxylic acids and amines. Its bulky pivaloyl group enhances stereoselectivity during crystallization or chromatography, making it effective for purifying enantiomerically pure compounds in asymmetric synthesis. Commonly employed in pharmaceutical research for preparing single-enantiomer intermediates where stereochemistry impacts biological activity. Also utilized in NMR spectroscopy to determine enantiomeric purity by inducing distinct chemical shifts for each enantiomer when formed into diastereomeric derivatives.
