Butanediol, also called butylene glycol, may refer to any one of four stable structural isomers:
Geminal diols
There are also two geminal diols (gem-diols), which are less stable:
Isobutylene glycol and methylpropanediol
Isobutylene glycol may be considered a kind of butylene glycol, similarly to butane historically including n-butane and i-butane (isobutane). The modern name for the closely related type of compounds is methylpropanediol. There are two stable structural isomers:
- 2-methylpropane-1,2-diol
- 2-methylpropane-1,3-diol
and one unstable geminal diol:
- 2-methylpropane-1,1-diol (not a glycol), hydrate of 2-methylpropanal (isobutyraldehyde)
These three methylpropanediols are structural isomers of butanediols. They are not chiral.
