Acetaldehyde dimethyl acetal is used as a flavoring agent. It is also used in the preparation of (R)-4,4-dimethoxy-2-butanol, pyrazoles and pyrimidines. Further, it is used in the preparation of N,N-diethyl-[2-(4-fluorophenyl)-5-methylpyrazolo[1,5-a]-pyrimidin-3-yl]acetamide and acetoacetaldehyde.
Protected form of the keto aldehyde, useful in heterocyclic synthesis, e.g. (formamide to 4-methylpyrimidine): Org. Synth. Coll., 5, 794 (1973).
