Molecule Details
Application
Chromogenic reagent for antimony in the low ppm range2 and for gallium and indium in the sub-ppm range.3
Biochem/physiol Actions
Potent inhibitor of osteoclastic bone resorption. The effect is believed to be attributable to both the antioxidant and estrogenic activities of kaempferol.1
