Slightly soluble in:methanol, ethanol, glycerol, ethylene glycol, formamide; insoluble in: acetone, toluene, heptane, diethyl ether, dichloromethane Pentaerythritol is an organic compound with the formula C(CH2OH)4.

The word pentaerythritol is a blend of penta- in reference to its five carbon atoms and erythritol, which also possesses 4 alcohol groups.

applications include alkyd resins, varnishes, polyvinyl chloride stabilizers, tall oil esters, antioxidants (e.g. Anox 20).

Relevant to resins, pentaerythritol is a precursor to other polyol, such as dipentaerythritol:[8] Esters of pentaerythitol are biodegradable,[9][10] and they are used as transformer oils.

[13][14] A linear polymer which can be described as a (spiro) orthocarbonate ester of pentaerythritol, whose formula could be written as [(−CH2)2C(CH2−)2 (−O)2C(O−)2]n, was synthesized in 2002.
