Used in the synthesis of biodegradable polymers and polyesters, glutaric acid serves as a building block for eco-friendly plastics. It is employed in the production of plasticizers to improve flexibility and durability of polymer materials. In organic synthesis, it acts as a precursor for various fine chemicals, including pharmaceuticals and agrochemicals. Glutaric acid also finds use in chelating metal ions, making it valuable in water treatment and industrial cleaning formulations. Additionally, it has applications in the development of corrosion inhibitors and in electroplating processes.
