Description

1-Chloro-4-Heptadecyne is a high-purity, long-chain aliphatic chloroalkyne building block of significant interest in advanced organic synthesis. This compound matters for its role as a versatile intermediate, enabling the introduction of both a reactive chloro group and an alkyne moiety into complex molecular architectures. It is needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty materials industries for constructing novel active ingredients and functional polymers.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the development of novel drug candidates, particularly for introducing lipophilic side chains or as a handle for click chemistry via the alkyne functionality.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides, where its long hydrocarbon chain can influence bioavailability and environmental persistence.
• Specialty Polymer & Material Science: Acts as a monomer or cross-linking agent in the synthesis of polymers with tailored properties, such as liquid crystals, coatings, and adhesives.
• Organic Synthesis Building Block: Employed in academic and industrial research for constructing complex natural products and novel organic molecules through Sonogashira coupling and other metal-catalyzed reactions.
• Surface Modification & Functionalization: Utilized to modify surfaces or nanoparticles, imparting specific chemical reactivity or hydrophobicity through the terminal alkyne and chloro groups.
• Lubricant & Fuel Additive Research: Investigated as a potential precursor for high-performance additives due to its long aliphatic chain structure.
