Description

General description

Glycerol formal (GlyF) includes isomers, namely, 4-hydroxymethyl-1,3-dioxolane and 5-hydroxy-1,3-dioxane. It is a glycerol synthon with a combination of two 5- and 6-membered ring isomers.

Application

Glycerol formal is used to to solubilize water-insoluble compounds for subsequent aqueous dilution. It has been used as a chemical and dye emulsifier and as a cosolvent for drug delivery. Glycerol formal was used as a vehicle for antibiotic delivery in rats.
