Glyceryl Behenate (Compritol 888 ATO)
CAS Number: 18641-57-1
Glyceryl Behenate (Compritol 888 ATO) is a mixture of glycerol mono-, di-, and tribehenate used as a lipid matrix former for sustained-release tablets and pellets, and as a lubricant in solid dosage forms. Its high melting point (65–77°C) enables melt granulation and hot melt extrusion processes. It provides pH-independent controlled release by forming a lipid barrier around the drug.
