Description

(E)-4-Nonen-1-Ol CAS NO 16695-34-4 is a high-purity, unsaturated fatty alcohol characterized by its distinct cis-3-hexenol-like green, fatty, and waxy odor profile. This compound serves as a valuable and versatile building block in the synthesis of complex fragrance molecules and specialty chemicals. It is primarily sought after by manufacturers in the flavor and fragrance industry for creating sophisticated green, melon, and cucumber notes, as well as by research and development laboratories for organic synthesis.

Application

• Fragrance Ingredient: A key intermediate and odorant for creating fresh, green, and fatty nuances in fine perfumery, personal care products, and air fresheners.
• Flavoring Agent: Used in the development of complex flavor profiles, particularly for imparting melon, cucumber, and fresh vegetable notes in food and beverage applications.
• Organic Synthesis Intermediate: A crucial building block in the production of more complex esters, ethers, and other derivatives for pharmaceutical and agrochemical research.
• Specialty Chemicals: Employed in the manufacture of surfactants, lubricant additives, and polymer modifiers where specific olefinic functionality is required.
• Research & Development: Serves as a standard or starting material in academic and industrial R&D for studying reaction mechanisms and developing new synthetic pathways.
