CH3CH25CHO

CH3CH25CHO, also known as heptanal or enanthaldehyde, is an organic compound with the chemical formula C7H14O. It is a straight-chain saturated aldehyde. Heptanal is a colorless liquid with a characteristic strong, fruity, and fatty odor. It is sparingly soluble in water but miscible with most organic solvents.

Heptanal occurs naturally in some essential oils, such as rose oil and coriander oil, contributing to their aroma. Industrially, it is produced through the oxidation of heptanol or by the hydroformylation of hexene. Its primary applications are in the fragrance and flavor industries, where it is used as a component in perfumes, cosmetics, and food flavorings. Due to its reactive aldehyde group, it can also serve as a starting material for the synthesis of other organic chemicals, including heptanoic acid and various derivatives. It is considered a relatively stable compound under normal conditions.
