Diol phase
A stationary phase useful in both normal and reversed-phase chromatography. Consists of a diol structure (two -OH groups on adjacent carbon atoms in an aliphatic chain). Less polar than silica stationary phases used in normal-phase chromatography has been used for the reversed-phase separation of proteins and polypeptides.

Diol
A diol or glycol is a chemical compound containing two hydroxyl groups (-OH groups). Vicinal diols have hydroxyl groups attached to adjacent atoms. Examples of vicinal diol compounds are ethylene glycol and propylene glycol. Geminal diols have hydroxyl groups bonded to the same atom. In general, organic geminal diols readily dehydrate to form a carbonyl group. For example, carbonic acid ((HO)2C=O) is unstable and has a tendency to convert to carbon dioxide (CO2) and water (H2O). Nevertheless, in rare situations the chemical equilibrium is in favor of the geminal diol. For example, when formaldehyde (H2C=O) is dissolved in water the geminal diol (H2C(OH)2), methanediol, is favored.
