diolcontaining

Diol-containing is a term used to describe molecules that include two hydroxyl groups (-OH) within the same structure. They are a subset of polyols and can range from simple small molecules to diol units in larger polymers. Diols are commonly classified by the arrangement of their hydroxyl groups: geminal diols, where both OH are on the same carbon; and vicinal diols, where the OH groups reside on adjacent carbons. Some diols occur within cyclic structures as well.

Geminal diols, such as methanediol, are generally unstable under typical conditions and tend to exist only

Properties and applications: The two hydroxyl groups enable extensive hydrogen bonding, which raises boiling points and

Chemistry and analysis: Diols participate in esterification and etherification reactions, facilitating polymer synthesis and functionalization. They
