Used primarily in organic synthesis, it serves as a key intermediate in the production of various pharmaceuticals and specialty chemicals. Its structure allows it to act as a building block for complex molecules, particularly in the development of active pharmaceutical ingredients (APIs). Additionally, it is employed in the creation of polymers and resins, where its dicarboxylic acid functionality contributes to the formation of durable materials. In research, it is utilized to study reaction mechanisms and develop new synthetic pathways. Its applications also extend to the field of agrochemicals, where it aids in the formulation of herbicides and plant growth regulators.
