Dipentaerythritol is an organic compound with the formula O[CH2C(CH2OH)3]2.

The molecular structure can be described as the ether derivative of pentaerythritol.

It is therefore a polyol, which are useful in the production of alkyd resins.

The compound is a by product in the production of pentaerythritol but also can be prepared intentionally from the latter:[1] Several thousand tons are produced annually.

Further condensations are possible, yielding tripentaerythritol, etc.
