Used in biochemical research to study protein synthesis and misfolding, as it can be mistakenly incorporated into proteins in place of proline, leading to altered protein structure and function. This property makes it a valuable tool for investigating diseases related to protein misfolding, such as neurodegenerative disorders.

Additionally, it serves as a starting material in the synthesis of cyclic compounds important in pharmaceutical development, particularly those with effects on the central nervous system or as enzyme inhibitors.

Also studied for its potential antifungal and antibacterial activities, particularly in plant defense mechanisms. It is naturally present in certain plants, such as legumes, acting as an antimicrobial agent. In agriculture, it serves as a natural herbicide due to its ability to interfere with amino acid metabolism in competing plant species, with potential for development as a biopesticide.
