Used as an intermediate in organic synthesis, particularly in the preparation of gamma-aminobutyric acid (GABA) analogs and pharmaceutical compounds. It serves as a building block for nitroalkane derivatives in medicinal chemistry. Also employed in the development of agrochemicals and specialty polymers due to its reactive nitro and carboxylic functional groups. Its structure allows for selective reductions and cyclization reactions, making it valuable in synthesizing heterocyclic compounds.
