Chemical Properties
LIGHT BEIGE TO TAN CRYSTALLINE POWDER
Uses
2-Methyl-1,3-cyclopentanedione hs been used to explore deoxycholic acid (DCA) induced changes in cell signaling. DCA is a secondary bile acid implicated in numerous pathological conditions. It has also been used in the synthesis of (-)-curcumanolide A and (-)-curcumalactone by aldol-lactonization.
Uses
2-Methyl-1,3-cyclopentanedione was used as a reactant in the identification and characterization of benzil (diphenylethane-1,2-dione) analogues as inhibitors of mammalian carboxylesterases.
