trans-2-Dodecenal
trans-2-Dodecenal, identified by CAS: 20407-84-5, is an unsaturated aliphatic aldehyde known for its distinct and powerful organoleptic properties. It occurs naturally in various botanical sources, most notably in coriander leaves (cilantro) and Eryngium foetidum, where it serves as a primary contributor to the characteristic pungent, green, and soapy aroma. In its isolated commercial form, it appears as a clear to slightly yellowish liquid that is highly prized in the flavor and fragrance industries for its potency and specific sensory profile.
This chemical compound is widely utilized as a flavoring agent due to its ability to impart a fresh, fatty, and citrus-like character to a variety of food products. Its chemical structure, featuring a trans-configured double bond at the C2 position, provides a reactive nature suitable for specialized organic syntheses. It is particularly effective at extremely low concentrations, providing a realistic herbal and earthy note that is difficult to replicate with other synthetic aldehydes.
• trans-2-Dodecenal is primarily employed as a high-impact flavoring agent in the food industry to create authentic cilantro and coriander flavor profiles. It is especially effective in savory applications, such as salsas, marinades, and ethnic spice blends, where a fresh green and slightly fatty note is required to mimic fresh herbs.
• In the fragrance sector, it serves as a sophisticated aromatic component for fine perfumes and daily-use personal care products. It adds a unique, fatty-floral, and waxy nuance that enhances citrus, green, and herbal accords, providing necessary depth and realism to complex scent compositions in soaps, lotions, and detergents.
• The compound is also studied and utilized in the development of agricultural insect pheromones and semiochemicals. Scientific research indicates that certain unsaturated aldehydes, including 2-dodecenal, play critical roles in the chemical communication and defense systems of various insect species, making it a valuable tool for sustainable pest management strategies.
• Beyond its flavoring and fragrance applications, this aldehyde acts as a versatile intermediate in organic synthesis. The reactive aldehyde functional group and the conjugated double bond allow for further chemical transformations to produce a variety of specialty chemicals, including alcohols and esters, used in fine chemical manufacturing and pharmaceutical research.
