Description

Eicosa-11-En-14-Ynoic Acid is a high-purity, long-chain fatty acid derivative featuring both an alkene and an alkyne functional group within its structure. This unique molecular architecture makes it a valuable and versatile building block in advanced organic synthesis and materials science research. It is primarily sought after by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for applications such as click chemistry, polymer modification, and the synthesis of bioactive lipid analogs.

Application

• Pharmaceutical Intermediate: Serves as a key synthon for the development of novel drug candidates, particularly in lipid-based therapeutics and targeted drug delivery systems.
• Click Chemistry Reagent: The alkyne moiety enables efficient, selective conjugation reactions (e.g., Copper-Catalyzed Azide-Alkyne Cycloaddition) for bioconjugation and polymer functionalization.
• Agrochemical Research: Used in the synthesis of novel surfactants, adjuvants, and active ingredients with tailored properties.
• Material Science: Acts as a monomer or cross-linking agent for creating specialty polymers, coatings, and liquid crystals with specific mechanical or optical characteristics.
• Biochemical Probe: Utilized in metabolic studies and as a tool compound to investigate lipid signaling pathways and enzyme functions.
• Cosmetic Ingredient Synthesis: A precursor for high-value emollients, moisturizers, and skin-barrier enhancing compounds.
