Description

Diethyl(5-Hexynyloxy)Borane is a specialized organoboron reagent featuring a terminal alkyne functional group, making it a valuable building block in synthetic organic chemistry. Its primary value lies in enabling efficient carbon-carbon bond formation, particularly in cross-coupling and hydroboration reactions. This compound is essential for researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require precise molecular construction for developing active ingredients and novel polymers.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the synthesis of complex drug candidates, especially those requiring alkyne or boron-containing moieties.
• Agrochemical Synthesis: Used in the production of novel pesticides and herbicides where the alkyne-borane functionality allows for selective derivatization.
• Material Science Research: Acts as a monomer or cross-linking agent in the development of boron-doped polymers and advanced organic electronic materials.
• Cross-Coupling Reactions: A crucial reagent in Suzuki-Miyaura and other palladium-catalyzed cross-coupling reactions to form biaryl and other complex structures.
• Hydroboration Processes: Utilized in the stereoselective hydroboration of alkenes and alkynes to create chiral alcohols and other functionalized molecules.
• Chemical Biology Probes: Employed in the synthesis of tagged molecules and probes for bio-conjugation and labeling studies via click chemistry.

Quality Control

Our Diethyl(5-Hexynyloxy)Borane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (¹H, ¹¹B, ¹³C) and GC/HPLC analysis, to ensure high chemical purity and consistency. Certificates of Analysis (COA) documenting identity, assay, and impurity profiles are available for every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container must be kept tightly sealed and handled in a moisture-free environment. Recommended storage temperature is 2-8°C for long-term stability.
