Examples include ethane-1,2-diol or ethylene glycol HO−(CH 2) 2 −OH, a common ingredient of antifreeze products. Another example is propane-1,2-diol, or alpha propylene glycol, HO−CH 2 −CH(OH)−CH 3, used in the food and medicine industry, as well as a relatively non-poisonous antifreeze product.
General structure of a 1,2-acetonide. The diol is shown in blue, the acetone part in red. In organic chemistry, an acetonide is the functional group composed of the cyclic ketal of a diol with acetone. The more systematic name for this structure is an isopropylidene ketal. Acetonide is a common protecting group for 1,2- and 1,3-diols. [1]
1,3-Propanediol is the organic compound with the formula CH 2 (CH 2 OH) 2. This 3-carbon diol is a colorless viscous liquid that is miscible with water. Products
1,3-Butanediol is an organic compound with the formula CH 3 CH(OH)CH 2 CH 2 OH, not to be confused with 1,4 Butanediol. With two alcohol functional groups, the molecule is classified as a diol . The compound without the R (or D) designation is racemic, which is what has been used in most studies before 2023.
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.
4-Methylcatechol (4-methylbenzene-1,2-diol) Orcinol (5-methylbenzene-1,3-diol) Methoxyphenols — can be derived from benzenediols by O-methylation. Guaiacol (2-methoxyphenol, O-Methylcatechol) Mequinol (4-Methoxyphenol) Dimethoxybenzenes — can be derived from benzenediols by two rounds of O-methylation. Veratrole (1,2-Dimethoxybenzene) 1,3 ...
General structure of 1,2-, 1,3-, and 1,4-dicarbonyls. In organic chemistry, a dicarbonyl is a molecule containing two carbonyl (C=O) groups.Although this term could refer to any organic compound containing two carbonyl groups, it is used more specifically to describe molecules in which both carbonyls are in close enough proximity that their reactivity is changed, such as 1,2-, 1,3-, and 1,4 ...
Example of a 1,2-diol (Ethyleneglycol, top),a 1,3-diol (1,3-Propanediol, middle)and a 1,4-diol (1,4-Butanediol, bottom).An alkanediol, composed of alkane and diol, are a group of substances consisting of linear or branched hydrocarbon chains containing exactly two hydroxy groups at different positions.
