butanediol

There are also two geminal diols (gem-diols), which are less stable:

• 1,1-Butanediol,{{cite web|url = https://pubchem.ncbi.nlm.nih.gov/compound/Butanediol|title=Butanediol|publisher=PubChem}} hydrate of butanal
• 2,2-Butanediol,{{cite web|url = https://pubchem.ncbi.nlm.nih.gov/compound/11469045|title=Propanediol, methyl-|publisher=PubChem}} hydrate of butanone

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.

2-Methylpropane-1,3-diol derivatives:

• Crisnatol, an experimental medication
• 2-Methyl-2-propyl-1,3-propanediol, medication precursor and active metabolite

• C4H10O2
• Diol
• Alkanediol
• Hydroxyl-substituted butanes
• Butyl alcohol
• Butanetriol
• Butanetetrol (butanetetraol), including 4-carbon sugar alcohols
• Erythritol
• Threitol
