Used as a chelating agent in analytical chemistry to detect and quantify metal ions, particularly in spectrophotometric methods. It forms stable complexes with metals like aluminum, iron, and copper, aiding in their identification and separation. In pharmaceuticals, it serves as an intermediate in the synthesis of antimicrobial and antifungal agents. It is also employed in organic synthesis to create derivatives with potential biological activities. Additionally, it finds use in the preparation of dyes and pigments due to its ability to form colored metal complexes. In agriculture, it is explored for its role in plant protection and as a growth regulator.
