Light yellow powder
The Uses of Chelidamic acid
Chelidamic acid hydrate has been used in eluent solution as a complexing additive in high-performance chelation ion chromatography (HPCIC) for speciation of iron. It has also been used as an organic ligand for the polyoxometalate (POM)-based lanthanoid hybrid compounds.
Biochem/physiol Actions
Among the most potent of the tested "conformationally restricted glutamate analogs" as an inhibitor of glutamate decarboxylase.
