Used as a selective chelating agent in analytical chemistry for the detection and separation of metal ions, particularly iron(III) and copper(II). Its structure allows strong coordination with transition metals, making it effective in spectrophotometric and electrochemical sensing applications. Also investigated for use in pharmaceutical formulations targeting metal-dependent enzymes due to its hydroxamic acid functionality, which can inhibit metalloproteins involved in disease processes. Shows potential in environmental chemistry for metal recovery and wastewater treatment.
