Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and antihistamines. Its structure allows for incorporation into larger molecules where a flexible, nitrogen-containing ring system is needed to enhance bioavailability or receptor binding. Also employed in the preparation of ion channel modulators and certain antiarrhythmic drugs. The compound's carboxylic acid group enables easy derivatization, making it valuable in medicinal chemistry for creating amides, esters, and peptide-like structures.
