Description

Potassium 3,5-Dibromophenyltrifluoroborate is an advanced organotrifluoroborate salt, a key building block in modern synthetic chemistry. Its primary value lies in its exceptional stability and reactivity, making it a superior reagent for Suzuki-Miyaura cross-coupling reactions compared to traditional boronic acids. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and materials science industries who require precise, high-yield carbon-carbon bond formation to create complex organic molecules.

Application

• Pharmaceutical Intermediate Synthesis: A critical precursor for constructing biaryl and heterobiaryl scaffolds found in active pharmaceutical ingredients (APIs).
• Agrochemical Development: Used in the synthesis of novel herbicides, fungicides, and insecticides requiring specific brominated aromatic structures.
• Ligand and Catalyst Preparation: Serves as a building block for creating specialized phosphine ligands and organometallic catalysts.
• Materials Science Research: Employed in the development of organic electronic materials, such as polymers for OLEDs and semiconductors.
• Chemical Biology Probes: Useful for labeling and modifying biomolecules due to its selective coupling chemistry.
• Scale-up Process Chemistry: Its air and moisture stability makes it suitable for robust, reproducible manufacturing processes.

Quality Control

Our Potassium 3,5-Dibromophenyltrifluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (¹H, ¹¹B, ¹⁹F), HPLC, and elemental analysis, to ensure identity, purity, and consistency. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment, supporting your regulatory and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, it is recommended to handle the material under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and to minimize exposure to ambient moisture. Recommended storage temperature: 2-8°C.
