4-ethyl cyclohexane propanal

4-ethyl cyclohexane propanal is a cyclohexane-based aldehyde characterized by a molecular structure consisting of an ethyl substitution on the cyclohexane ring combined with a propanal functional group. This compound is recognized for its strong floral and green odor notes, often described as reminiscent of muguet or lily of the valley. Chemically, it belongs to the family of aliphatic aldehydes with a cycloalkane substituent. Known synonyms include 4-ethyl cyclohexane propionaldehyde, 4-ethyl cyclohexanepropanal, and 4-ethyl cyclohexanepropionaldehyde. It is derived primarily through synthetic organic chemistry routes targeting fragrance creation. For chemical reference, see its entry in the PubChem database. This compound is not naturally abundant but is valued for its odorant properties in perfumery and related industries.

4-ethyl cyclohexane propanal does not commonly occur in nature but is synthetically produced for use predominantly as a fragrance agent. This compound's floral and green odor profile makes it suitable for incorporation into perfume formulations where fresh and natural scent impressions are desired. Industry standards such as IFRA (Global) govern the use of this and related fragrance materials, recommending appropriate concentration limits to ensure consumer safety. It is not approved for flavoring purposes and is restricted solely to fragrance applications. Its distinctive aroma contributes to a range of olfactory experiences important to commercial fragrance blending.

The chemical properties of 4-ethyl cyclohexane propanal include typical aldehyde reactivity and moderate volatility, which facilitate its use in fragrance compositions. Its cyclohexane ring imparts lipophilicity, affecting solubility in oils and organic solvents commonly used in perfumery. The ethyl substituent on the cyclohexane ring influences molecular shape and odor conformation. These properties combine to deliver a strong and persistent floral scent with green undertones. The molecular structure and physicochemical behavior require careful formulation consideration to optimize scent release and stability under ambient conditions.
