Description

15-Octadecenal is a high-purity, long-chain unsaturated aldehyde of significant interest in advanced organic synthesis and fragrance chemistry. Its unique structure makes it a valuable intermediate for creating complex molecules, including pheromones, flavorants, and specialty surfactants. This compound is essential for R&D laboratories and production facilities in the fragrance, flavor, and fine chemical industries seeking to develop novel compounds with specific olfactory or functional properties.

Application

• Fragrance & Flavor Intermediate: A key building block for synthesizing complex aroma chemicals and natural product analogs.
• Pheromone Synthesis: Used in the research and production of insect pheromones for agricultural pest management.
• Specialty Surfactants: Serves as a precursor for synthesizing novel surfactants with specific hydrophilic-lipophilic balance (HLB) properties.
• Organic Synthesis: A versatile intermediate in organic chemistry for carbon chain elongation and the introduction of aldehyde functionality.
• Biochemical Research: Used in studies of lipid peroxidation and as a standard or reagent in analytical chemistry.
• Lubricant & Polymer Additives: Potential intermediate for creating specialized additives that modify the properties of oils and polymers.

Quality Control

Our 15-Octadecenal is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. We employ advanced analytical techniques including GC, HPLC, and NMR for identity confirmation and impurity profiling. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and specific tests is provided with each shipment to support your quality assurance and regulatory needs.

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 place. Recommended storage temperature is 2-8°C for long-term stability. Allow the container to reach room temperature before opening to minimize moisture condensation.
