1,4-Butanediol, also called butane-1,4-diol (other names include 1,4-B, BD, BDO, and 1,4-BD), is a primary alcohol and an organic compound with the formula HOCH2CH2CH2CH2OH. It is a colorless viscous liquid first synthesized in 1890 via acidic hydrolysis of N,N'-dinitro-1,4-butanediamine by Dutch chemist Pieter Johannes Dekkers, who called it "tetramethylene glycol".

1,3-Propanediol is the organic compound with the formula . This 3-carbon diol is a colorless viscous liquid that is miscible with water.

Pinacol is a branched alcohol which finds use in organic syntheses. It is a diol that has hydroxyl groups on vicinal carbon atoms. A white solid that melts just above room temperature, pinacol is notable for undergoing the pinacol rearrangement in the presence of acid and for being the namesake of the pinacol coupling reaction.

1,3-Butanediol is an organic compound with the formula CH3CH(OH)CH2CH2OH, 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. The compound is a colorless, bittersweet, water-soluble liquid. It is one of four common structural isomers of butanediol. It is used in grape flavoring, and as a precursor to some antibiotics.

1,2-Butanediol is the organic compound with the formula HOCH(HO)CHCHCH. It is classified as a vic-diol (glycol). It is chiral, although typically it is encountered as the racemic mixture. It is a colorless liquid.

1,5-Pentanediol is the organic compound with the formula HO(CH)OH. Like other diols, this viscous, colorless liquid is used as a plasticizer and also forms polyesters, which are used as emulsifying agents and resin intermediates.

1,6-Hexanediol is an organic compound with the formula (CH2CH2CH2OH)2. It is a colorless water-soluble solid.

2,3-Butanediol is the organic compound with the formula (CH3CHOH)2. It is classified as a vic-diol (glycol). It exists as three stereoisomers, a chiral pair and the meso isomer. All are colorless liquids. Applications include precursors to various plastics and pesticides.

Butanediol, also called butylene glycol, may refer to any one of four stable structural isomers:

chemical compound

Etohexadiol (or ethohexadiol) is an ectoparasiticide. It was known as the insect repellent "6-12" (Six-twelve), or Rutgers 612. Its use in the U.S. was halted in 1991 after it was shown to cause developmental defects in animals.

1,8-Octanediol, also known as octamethylene glycol, is a diol with the molecular formula HO(CH)OH, a white solid. It can be produced with high purity by hydrogenation of esters of suberic acid.

2-Methyl-2,4-pentanediol (MPD) is an organic compound with the formula (CH3)2C(OH)CH2CH(OH)CH3. This colourless liquid is a chiral diol. It is produced industrially from diacetone alcohol by hydrogenation. Total European and USA production was 15000 tonnes in 2000.

2,5-Hexanediol is an organic compound with the formula CH3CH(OH)CH2CH2CH(OH)CH3. It is both a glycol and a secondary alcohol. It is a colorless water-soluble viscous liquid. The chemical properties are well understood and have been extensively reported and studied. It has the IUPAC name of hexane-2,5-diol and the CAS Registry Number CAS 2935-44-6.

Prenderol (Diethylpropanediol) is a simple alkyl diol which has sedative, anticonvulsant and muscle relaxant effects. It is closely related in structure to meprobamate and numerous other alkyl alcohols and diols with generally comparable activity.

1,9-Nonanediol, also known as nonamethylene glycol, is a diol with the molecular formula HO(CH)OH. It is a colorless solid, which is sparingly soluble in water but readily soluble in ethanol.

1,2-Octanediol, also known as caprylyl glycol, is a diol with the molecular formula CH(CH)CHOHCHOH.

1,10-Decanediol is an organic compound diol with the chemical formula . It is a white solid with limited solubility in water. The molecular configuration of 1,10-decanediol is described as having a zigzag conformation.

"Alkane" is a type of hydrocarbon containing no cyclic carbon structures and only carbon-carbon single bonds, meaning only linear or branched carbon chains; alkanes are also completely saturated, meaning that all carbon bonding positions which are not carbon-carbon bonds are occupied by hydrogen.
