Used as a key intermediate in the synthesis of nylon-7, a biodegradable polymer with applications in specialty plastics and fibers. Serves as a building block in pharmaceuticals, particularly in the development of peptide-like structures and drug conjugates due to its amino and carboxylic functional groups. Employed in research for creating novel polyamides and hydrogels with tailored properties for biomedical uses. Also utilized in the preparation of surfactants and surface-modifying agents where controlled chain length and polarity are required.
