Widely used in agriculture as a micronutrient source to correct copper deficiency in soils, especially in crops sensitive to copper uptake. It enhances plant growth and prevents disorders like wilting and chlorosis. In industrial settings, it serves as a stabilizer in water treatment processes, helping control metal ion activity and prevent oxidative degradation. Also employed in analytical chemistry as a complexing agent in spectrophotometric and titration methods for metal ion determination. Its chelating properties make it effective in reducing interference from other metal ions in biochemical assays.
