22dimethyl3hydroxypropanal

2,2-dimethyl-3-hydroxybutanal, also known as hydroxypivalaldehyde, is an organic compound with the chemical formula C6H12O2. It is a colorless liquid at room temperature and has a relatively low melting point. The molecule features a branched six-carbon chain with a hydroxyl group attached to the third carbon and an aldehyde group at the end of the chain. Its structure can be visualized as a derivative of pivalaldehyde where a hydroxyl group has been introduced.

This compound is an intermediate in various chemical syntheses. It can be produced through the aldol reaction of isobutyraldehyde. The presence of both a hydroxyl and an aldehyde functional group makes it a versatile building block for creating more complex organic molecules. For example, it can undergo further reactions like oxidation, reduction, or condensation. Its specific applications are often found in the synthesis of pharmaceuticals, fragrances, and polymers, where its unique structure can impart desired properties to the final product. The precise reactivity of 2,2-dimethyl-3-hydroxybutanal is influenced by the steric hindrance provided by the geminal dimethyl groups adjacent to the aldehyde.
