Used as an intermediate in organic synthesis, particularly in the development of pharmaceutical compounds. It serves as a building block for peptide-like structures due to its diketopiperazine core, which is known for enhancing metabolic stability and bioavailability in drug candidates. Commonly applied in research settings for designing bioactive molecules, including those with potential neurological or antimicrobial activity. Also utilized in the preparation of ligands for receptor binding studies, especially in central nervous system-related drug discovery.
