triol

A triol is an organic compound that contains three hydroxyl groups (-OH). As a subclass of polyols, triols can have the three hydroxyls on adjacent carbons or on different parts of the molecule. They are typically polar and capable of extensive hydrogen bonding, often with relatively high boiling points and varying degrees of water solubility.

The best-known triol is glycerol, or propane-1,2,3-triol. It is a colorless, viscous liquid that is miscible with

Other triols include trimethylolpropane (TMP), used as a crosslinking agent in polyurethane resins, and aromatic triols

In polymer chemistry, triols act as polyols, facilitating crosslinking and chain extension in polyurethane foams and
