white to beige crystalline powder or flakes | [Uses]
4-Pentynoic Acid is a hypoglycemic agent shown to increase liver tyrosine aminotransferase and plasma corticosterone while decreasing blood sugar in rats. | [General Description]
4-Pentynoic acid undergoes copper-catalyzed intramolecular cyclizations to form enol lactones. It also reacts with 1-bromo-1-alkynes in the presence of a Pd catalyst to yield biologically active ynenol lactones. |
