• Uses: Indicator for complexometric titrations. Murexide is used as a complexometric indicator in analytical chemistry for complexometric titrations of calcium, copper nickel and cobalt. It is an inhibitor of dihydrofolate reductase. Further, it acts as an enhancer of sonochemical destruction of chlorinated hydrocarbon pollutants.

Technology Process of Murexide

There total 29 articles about Murexide which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use.
