Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antihistamines and other bioactive molecules. Serves as a building block in organic synthesis due to the presence of reactive amine groups. Employed in the preparation of chelating agents that bind metal ions, useful in water treatment and analytical chemistry. Also utilized in the development of specialty polymers and resins where controlled cross-linking is required. Its salt form enhances stability and handling in industrial processes.
