This aldehyde 2-cyclohexylacetaldehyde finds some use in perfumery, although only in certain types of fragrances for household products, etc. Its odor type is not suitable for finer perfumes, except as a minor ingredient in aldehydic topnote compositions. Its power and low cost makes it an attractive item for the volume fragrances intended for detergents, room-sprays, cleaners, etc. It gives pleasant and refreshing effects in Pine needle fragrances, and performs well with all the Citrus oils.

2-cyclohexylacetaldehyde is produced from Butadiene by condensation with Crotonaldehyde, followed by hydrogenation.
