What’s the application of pantolactone?
Dihydro-3-hydroxy-4,4-dimethyl-2(3H)furanone is a chemical substance and an intermediate of mixed spiral calcium pantothenate. It is used as a pharmaceutical intermediate for the synthesis of calcium D-pantothenate and D-panthenol. The latter is further condensed and hydrolyzed, acidified, and lactonized with hydrocyanic acid with the participation of calcium chloride to produce the product.
