2Hydroxy2methylpropanal

2Hydroxy2methylpropanal, also known as hydroxypivalaldehyde, is an organic compound with the chemical formula C5H10O2. It is a colorless liquid at room temperature. This molecule contains both a hydroxyl group (-OH) and an aldehyde group (-CHO) attached to a quaternary carbon atom. The presence of these two functional groups makes it a reactive intermediate in organic synthesis.

Hydroxypivalaldehyde is primarily used as a building block in the synthesis of more complex molecules. It can participate in various reactions, including oxidation, reduction, and condensation. One notable application is its role in the production of certain pharmaceuticals and specialty chemicals. Its unique structure, with a tertiary alcohol and an aldehyde on the same carbon, imparts specific reactivity that is valuable in chemical manufacturing processes. It is typically synthesized through the oxidation of neopentyl glycol or via a Prins reaction. Due to its reactive nature, it is often handled with care and stored appropriately to maintain its purity and prevent degradation.
