Used as a corrosion inhibitor in cooling water systems and industrial boilers due to its ability to form protective films on metal surfaces. Also serves as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and dyes. Employed in the preparation of chelating agents for metal ions in wastewater treatment. Acts as a building block in the production of fungicides and herbicides. Utilized in coordination chemistry as a ligand for transition metal complexes in catalysis. Found in some antimicrobial formulations for its biocidal properties.
