Description

2-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)-4-(Trifluoromethyl)Benzonitrile is a high-value organoboron building block, specifically a pinacol boronic ester, designed for advanced synthetic chemistry. Its core value lies in enabling efficient Suzuki-Miyaura cross-coupling reactions, a cornerstone methodology for constructing complex carbon-carbon bonds in pharmaceutical and agrochemical research. This compound is essential for medicinal chemists and process R&D teams developing novel active ingredients, particularly those targeting the incorporation of the versatile trifluoromethyl group into molecular scaffolds.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs), especially for candidates containing aryl-trifluoromethyl motifs.
• Agrochemical Synthesis: Used in the research and development of advanced herbicides, fungicides, and insecticides where the benzonitrile and CF3 groups are critical for bioactivity.
• Material Science Research: Serves as a precursor for creating functionalized organic molecules used in organic light-emitting diodes (OLEDs) and liquid crystal displays (LCDs).
• Suzuki-Miyaura Cross-Coupling: The primary application is as a stable, air-handleable boronic ester reagent for palladium-catalyzed coupling with aryl/vinyl halides or triflates.
• Chemical Biology Probes: Utilized in the design and synthesis of molecular probes and tags for studying biological systems and drug-target interactions.
• Complex Molecule Construction: Enables the modular assembly of biaryl and heterobiaryl structures that are difficult to access via other synthetic routes.

Quality Control

Our 2-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)-4-(Trifluoromethyl)Benzonitrile is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via NMR and IR spectroscopy, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) with detailed specifications are available upon request for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) 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 humidity. Ideal storage temperature is 2-8°C for extended stability.
