Description

9-Octadecenal is a long-chain unsaturated aldehyde of significant industrial interest. This compound serves as a versatile intermediate and building block in the synthesis of more complex organic molecules. It is particularly valuable for manufacturers in the fragrance, flavor, and specialty chemical industries seeking to create or modify specific organoleptic profiles and functional properties.

Application

• Fragrance and Flavor Intermediate: A key precursor in the synthesis of musks, floral, and fatty aldehydic notes for perfumery and food flavoring applications.
• Specialty Chemical Synthesis: Used as a building block for producing surfactants, lubricant additives, and plasticizers through reactions like oxidation, reduction, or condensation.
• Pharmaceutical Research: Acts as a chiral intermediate or a starting material in the research and development of bioactive compounds and active pharmaceutical ingredients (APIs).
• Agrochemical Formulations: Employed in the synthesis of pheromones, plant growth regulators, and other agrochemical agents.
• Material Science: Investigated for use in polymer cross-linking agents and as a modifier for surface properties in advanced materials.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, minimize headspace in opened containers and handle under an inert gas blanket for long-term stability.
