Description

1-Chloro-6-Heptadecyne is a specialized aliphatic chloroalkyne building block of significant interest in advanced organic synthesis. This compound matters for its unique bifunctional reactivity, offering both a terminal alkyne group and a chloroalkyl chain for selective coupling and chain extension reactions. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and materials science industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the development of novel active pharmaceutical ingredients (APIs), particularly for creating long-chain hydrocarbon tethers or functionalized side chains.
• Agrochemical Synthesis: Used in the research and production of specialized pesticides and herbicides where specific alkyne-containing hydrophobic moieties are required for bioactivity.
• Material Science Research: Acts as a monomer or cross-linking agent in the synthesis of advanced polymers, liquid crystals, or surface-modifying agents.
• Organic Synthesis Building Block: Employed in Sonogashira coupling, click chemistry (azide-alkyne cycloaddition), and other metal-catalyzed cross-coupling reactions to introduce a 17-carbon chain with a terminal reactive handle.
• Lubricant & Fuel Additive Precursor: Investigated for the synthesis of novel friction modifiers or viscosity index improvers due to its long hydrocarbon backbone.
