Description

1-Octyne (CAS NO 629-05-0) is a terminal alkyne characterized by its eight-carbon chain and a reactive triple bond at the terminal position. This structure makes it a valuable building block in organic synthesis, particularly for carbon-carbon bond formation and the creation of more complex molecular architectures. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries who require high-purity intermediates for advanced R&D and production.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the synthesis of active pharmaceutical ingredients (APIs) and complex organic molecules.
• Agrochemical Synthesis: Used in the production of advanced crop protection agents and herbicides.
• Material Science Research: Acts as a monomer or precursor in the development of polymers and advanced materials with specific properties.
• Organic Synthesis & Catalysis: A fundamental reagent for coupling reactions (e.g., Sonogashira, Glaser coupling) and as a ligand precursor in organometallic chemistry.
• Flavor & Fragrance Industry: Employed in the synthesis of specific aroma chemicals and odorants.
• Laboratory Reagent: Used as a standard or reference compound in analytical chemistry and academic research.
