Description

8-Octadecenal is a long-chain unsaturated aldehyde of significant interest in organic synthesis and fragrance chemistry. This compound serves as a versatile intermediate for the production of flavor and fragrance ingredients, pharmaceuticals, and specialty surfactants. It is particularly valuable for research and development in the flavor & fragrance, cosmetic, and fine chemical industries seeking to create or modify specific organoleptic profiles.

Application

• Flavor and Fragrance Intermediate: A key building block for synthesizing musk analogs, floral, and fatty aldehydic notes in perfumery and flavor compositions.
• Organic Synthesis: Used in various reactions, including reduction to alcohols, oxidation to acids, or as a substrate for Wittig and Grignard reactions to create more complex molecules.
• Surfactant and Detergent Precursor: Can be converted into derivatives used in the formulation of specialty surfactants, emulsifiers, and cleaning agents.
• Pharmaceutical Research: Employed as a chiral intermediate or a starting material in the synthesis of bioactive compounds and lipid-based drug delivery systems.
• Material Science: Acts as a monomer or cross-linking agent in polymer research for creating novel polymeric materials with specific properties.
• Biochemical Studies: Used in research related to lipid peroxidation, membrane chemistry, and as a standard in analytical chromatography.

Quality Control

Our 8-Octadecenal is produced and tested under a strict quality management system to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) for each batch, detailing key parameters such as identity, assay, and impurity profiles. For customers with specific regulatory needs, we can discuss compliance with relevant standards and support documentation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area at 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.
