Description

11-Dodecynoic Acid Methyl Ester is a high-purity alkyne-functionalized fatty acid ester, a valuable building block in organic synthesis. Its terminal alkyne group makes it a critical intermediate for click chemistry, particularly in the synthesis of complex molecules and advanced materials. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries seeking to introduce specific functional groups or create novel molecular architectures.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates via Huisgen cycloaddition (click chemistry).
• Agrochemical Synthesis: Serves as a key precursor for creating novel pesticides, herbicides, and plant growth regulators with tailored properties.
• Material Science & Polymer Chemistry: A monomer for synthesizing specialty polymers, dendrimers, and functionalized surfaces with alkyne handles for further modification.
• Liquid Crystal & OLED Research: Employed in the development of advanced organic electronic materials and display components.
• Cross-Coupling Reactions: Acts as a substrate in Sonogashira and other palladium-catalyzed coupling reactions to form carbon-carbon bonds.
• Bioconjugation & Probe Development: Useful for labeling biomolecules (proteins, nucleic acids) with fluorescent or other reporter tags in diagnostic applications.
