Used as a key intermediate in the synthesis of nylon-8, a polyamide with applications in specialty plastics and fibers. Its amino and carboxylic acid functional groups allow it to act as a monomer in polymerization reactions, contributing to the development of biodegradable polymers and tailored macromolecules for use in medical devices and drug delivery systems. Also employed in the preparation of surfactants, corrosion inhibitors, and surface coatings due to its amphiphilic properties. Its structure supports conjugation in bioactive molecules, making it useful in pharmaceutical research and the design of peptide-like compounds.
