1nonanal

1nonanal is a chemical compound with the formula C9H18O. It is an aldehyde, characterized by the presence of a formyl group (-CHO) attached to a nonyl chain. This makes it a saturated fatty aldehyde. 1nonanal is a colorless liquid at room temperature and possesses a distinct waxy, citrusy odor. It is naturally occurring and has been identified as a component in some essential oils and food aromas, contributing to their characteristic scents.

Industrially, 1nonanal is produced through the oxidation of 1-nonanol or by hydroformylation of 1-octene. Its primary uses are as a fragrance ingredient in perfumes, soaps, and detergents, and as a flavoring agent in food products where its citrusy notes are desired. It can also serve as an intermediate in the synthesis of other organic chemicals, including nonanoic acid and its derivatives, which have applications in lubricants and plastics. While generally considered safe for its intended uses in consumer products and food, like many chemicals, prolonged or excessive exposure should be avoided.
