Used as a corrosion inhibitor for metals in acidic environments, particularly effective in protecting steel surfaces during pickling and cleaning processes. Also serves as an intermediate in the synthesis of heterocyclic compounds with potential biological activity, including antimicrobial, antifungal, and antioxidant agents. Its structure allows coordination with metal ions, especially transition metals like copper, silver, and nickel, making it useful in analytical chemistry for metal ion sensing and extraction, including colorimetric detection for heavy metals in environmental samples. Additionally, it has been investigated for use in pharmaceutical research due to its ability to modulate enzyme activity.
