Description

1-Hepten-4-Yne is a high-purity, unsaturated hydrocarbon building block characterized by its unique combination of an alkene and an alkyne functional group within a seven-carbon chain. This bifunctional structure makes it a valuable and versatile intermediate for advanced organic synthesis, particularly in the development of specialty polymers, fine chemicals, and complex molecular architectures. It is essential for research and industrial chemists in the pharmaceutical, agrochemical, and materials science sectors seeking to introduce specific linear frameworks or reactive handles into their target molecules.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the synthesis of novel active pharmaceutical ingredients (APIs) and complex organic molecules for medicinal chemistry research.
• Agrochemical Synthesis: Used in the production of advanced crop protection agents and specialty herbicides, leveraging its reactive sites for structural diversification.
• Polymer & Material Science: Acts as a monomer or co-monomer for creating specialty polymers with tailored properties, such as modified polyolefins or cross-linked networks.
• Fine Chemical Production: Employed in the manufacture of flavors, fragrances, and other high-value specialty chemicals requiring specific carbon chain lengths and unsaturation.
• Organic Synthesis Building Block: Utilized in cross-coupling reactions (e.g., Sonogashira, Heck) and cycloadditions to construct complex organic frameworks in academic and industrial R&D.
• Ligand & Catalyst Development: Functions as a precursor for synthesizing novel ligands and organometallic complexes used in catalytic processes.

Quality Control

Our 1-Hepten-4-Yne is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC, GC-MS, and NMR, to ensure high chemical purity and identity confirmation. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all relevant specifications. Our quality commitment ensures material consistency and reliability for your critical synthesis and production processes.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated place, away from heat, sparks, and open flame. Due to its highly volatile and easily oxidized nature, it is recommended to store at 2-8°C for extended stability. Keep container tightly sealed when not in use to prevent evaporation and degradation.
