Description

cis-11-Hexadecenal is a high-purity, unsaturated aliphatic aldehyde with the CAS number 53939-28-9. This compound is a critical intermediate and active ingredient in the synthesis of complex organic molecules, particularly in the field of pheromone research and production. It is essential for manufacturers and R&D laboratories in the agrochemical, flavor & fragrance, and fine chemical sectors who require precise, high-quality building blocks for specialty formulations.

Application

• Pheromone Synthesis: A key component in the production of insect sex pheromones for integrated pest management (IPM) and eco-friendly agricultural solutions.
• Flavor & Fragrance Industry: Serves as a valuable intermediate for creating specific green, waxy, or aldehydic notes in premium fragrance compositions and flavor agents.
• Organic Synthesis: Used as a versatile chiral building block in the synthesis of complex natural products, pharmaceuticals, and liquid crystal materials.
• Biochemical Research: Employed in studies of insect olfaction, receptor-ligand interactions, and the development of behavioral attractants or repellents.
• Fine Chemical Manufacturing: Acts as a precursor for surfactants, lubricant additives, and other specialty chemicals requiring specific long-chain aldehyde functionality.
