Used as a chelating agent in organic synthesis and catalysis, particularly in metal-mediated reactions where controlled coordination is required. Its ester groups enhance solubility in non-aqueous solvents, making it suitable for use in lipophilic environments. Commonly employed in the preparation of metal complexes for catalytic applications, such as oxidation or polymerization reactions. Also finds use in analytical chemistry for masking metal ions in non-polar matrices. Due to its masked acidity, it is occasionally applied in formulations where pH stability is critical.
