Pivalaldehyde (Cat No.:R005186) is a branched aliphatic aldehyde characterized by a tert-butyl group attached to a formyl functional group. This sterically hindered structure imparts unique reactivity, making it useful in organic synthesis, particularly in the preparation of bulky ligands, resins, and specialty chemicals. Pivalaldehyde is valued for its selective reactivity in condensation and nucleophilic addition reactions. It is typically a colorless, volatile liquid with a pungent odor, soluble in organic solvents, and should be handled under anhydrous conditions due to its sensitivity to oxidation and moisture.
