Pentaerythritol is an organic compound with the formula C5H12O4. This white, crystalline polyol with theneopentane backbone is a versatile building block for the preparation of many polyfunctionalized
compounds such as the explosive pentaerythritol tetranitrate and pentaerythritol tetraacrylate.Derivative
s of pentaerythritol are components of alkyd resins, varnishes, polyvinyl chloride stabilizers, tall oil esters,
and olefin antioxidants.
