Description

18-Bromo-6,9-octadecadiene is a valuable brominated long-chain diene intermediate with a reactive allylic bromide moiety. This compound matters for its utility as a versatile building block in organic synthesis, enabling the introduction of the C18 chain and facilitating further functionalization via nucleophilic substitution or coupling reactions. It is needed by researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for developing active ingredients, liquid crystals, and advanced polymeric materials.

Application

• Pharmaceutical Intermediate: Serves as a key synthon for the synthesis of complex drug molecules and bioactive compounds.
• Agrochemical Synthesis: Used in the production of specialized pesticides, herbicides, and plant growth regulators.
• Liquid Crystal Precursor: Acts as a starting material for the synthesis of mesogenic compounds used in display technologies.
• Polymer Modification: Employed to introduce long alkyl chains or reactive sites into polymers for specialty material applications.
• Organic Synthesis Building Block: Utilized in cross-coupling reactions (e.g., Suzuki, Heck) and nucleophilic substitutions to construct more complex organic architectures.
• Surfactant & Lubricant Additive Research: Investigated for the development of novel surfactants and lubricant additives due to its hydrophobic chain.
