Description and Uses
Pentaerythritol is a versatile starting material to synthesize various dendrimers and star-shaped polymers. It is widely used in the preparation of flame-retardant epoxy resins and polymer composites. It is also used in the synthesis of the vasodilator, pentaerythritol tetranitrate (PETN).
