Description

Ethenyl-Difluoro-Borane is a highly reactive organoboron compound, primarily valued as a versatile reagent in advanced synthetic chemistry. Its core value proposition lies in its ability to act as a key building block for introducing boron and fluorine-containing functional groups into complex molecular architectures. This makes it an essential material for research and development chemists in the pharmaceutical, agrochemical, and materials science industries seeking to create novel compounds with specific properties.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of boron-containing drug candidates, particularly for Boron Neutron Capture Therapy (BNCT) and protease inhibitors.
• Agrochemical Synthesis: Used to create novel pesticides and herbicides by incorporating boron-fluorine motifs that can enhance biological activity and environmental stability.
• Polymer & Materials Science: Serves as a monomer or cross-linking agent for developing specialty polymers, resins, and advanced materials with unique thermal or electronic properties.
• Organic Synthesis Reagent: Employed in hydroboration reactions, Suzuki-Miyaura cross-coupling, and as a source of vinyl and difluoroborane groups in complex molecule construction.
• Electronics & Semiconductor Precursor: Investigated as a potential precursor for chemical vapor deposition (CVD) of boron-containing thin films used in electronic devices.
• Catalysis Research: Utilized in the development and study of new organoboron catalysts for asymmetric synthesis and other catalytic processes.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this compound must be stored under an inert atmosphere (argon or nitrogen) at recommended temperatures between 2°C and 8°C. The storage area should be cool, dry, and well-ventilated, away from sources of ignition and incompatible materials such as strong oxidizers, acids, and bases.
