It is classified as an aldol (R−CH(OH)−CHR'−C(=O)−R") and the word "aldol" can refer specifically to 3-hydroxybutanal. It is formally the product of the dimerization of acetaldehyde (CH 3 CHO). A thick colorless or pale-yellow liquid, it is a versatile and valuable intermediate with diverse impacts. [2]

Lactonitrile is the organic compound with the formula CH 3 CH(OH)CN. It is an intermediate in the industrial production of ethyl lactate and lactic acid. [1] [2] [3] It is the cyanohydrin of acetaldehyde. It is a colorless liquid, although degraded samples can appear yellow.
Propylene glycol (IUPAC name: propane-1,2-diol) is a viscous, colorless liquid. It is almost odorless and has a faintly sweet taste. Its chemical formula is CH 3 CH(OH)CH 2 OH. As it contains two alcohol groups, it is classified as a diol. An aliphatic diol may also be called a glycol.
An example is the pair propanal H 3 C–CH 2 –C(=O)-H and acetone H 3 C–C(=O)–CH 3: the first has a –C(=O)H functional group, which makes it an aldehyde, whereas the second has a C–C(=O)–C group, that makes it a ketone. Another example is the pair ethanol H 3 C–CH 2 –OH (an alcohol) and dimethyl ether H 3 C–O–CH 2 H (an ether).
3 CH(OH)CO − 2. Compared to acetic acid, its pK a is 1 unit less, meaning lactic acid is ten times more acidic than acetic acid. This higher acidity is the consequence of the intramolecular hydrogen bonding between the α-hydroxyl and the carboxylate group. Lactic acid is chiral, consisting of two enantiomers.
Crotonaldehyde is a chemical compound with the formula CH 3 CH=CHCHO. The compound is usually sold as a mixture of the E- and Z-isomers, which differ with respect to the relative position of the methyl and formyl groups.
[2]: 4 [4] It is predominantly used as a precursor to trimethylolethane (CH 3 C(CH 2 OH) 3) through a condensation reaction with formaldehyde. This triol is an important intermediate in the production of alkyd resins. It is used in the synthesis of several common aroma compounds (cyclamen aldehyde, helional, lilial). [2]
