Description

1-Hexen-4-Yne is a highly reactive, low molecular weight aliphatic hydrocarbon featuring both a terminal alkyne and an alkene functional group. This unique structure makes it a valuable and versatile building block in advanced organic synthesis and materials science. It is primarily sought after by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for creating novel molecular architectures.

Application

• Pharmaceutical Intermediates: Serves as a key precursor in the synthesis of complex drug molecules and active pharmaceutical ingredients (APIs), leveraging its dual reactivity for cyclization and functionalization reactions.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and plant growth regulators that require specific alkyne-alkene motifs.
• Specialty Polymer & Material Science: Acts as a monomer or cross-linking agent in the development of advanced polymers with tailored properties, such as conductive materials or specialty adhesives.
• Organic Synthesis & Catalysis Research: A fundamental reagent in academic and industrial laboratories for studying novel metal-catalyzed coupling reactions, including Sonogashira and hydroamination.
• Flavor & Fragrance Industry: Potential intermediate for synthesizing specific unsaturated compounds that contribute to unique scent or flavor profiles.
• Chemical Derivatization: Employed to introduce reactive handles onto larger molecules or surfaces for further chemical modification in sensor technology or diagnostics.

Quality Control

Every batch of 1-Hexen-4-Yne is produced and analyzed under strict quality protocols to ensure consistency and reliability for your critical applications. We provide comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles, typically determined by GC, GC-MS, and NMR. Our quality management system is designed to meet the stringent requirements of research and fine chemical synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C in a cool, dry, well-ventilated place, away from heat and ignition sources. Due to its highly volatile and easily oxidized nature, containers must be kept tightly sealed and should be allowed to reach ambient temperature before opening to minimize moisture ingress and pressure changes.
