Description

3-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)-5-(Trifluoromethyl)Benzonitrile is a high-value, multi-functional boronic ester derivative, serving as a critical synthetic intermediate in modern organic chemistry. Its core value lies in enabling precise carbon-carbon bond formation via Suzuki-Miyaura cross-coupling reactions, a cornerstone technology for constructing complex molecular architectures. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors, where it is used to introduce the versatile 5-(trifluoromethyl)benzonitrile moiety into target molecules.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly those containing trifluoromethyl groups which enhance metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and insecticides, leveraging the biological activity of the trifluoromethyl and nitrile functionalities.
• Material Science Research: Serves as a precursor for organic electronic materials, such as OLED (Organic Light-Emitting Diode) emitters and charge transport materials, where its structure allows for fine-tuning of electronic properties.
• Ligand and Catalyst Development: Employed in the creation of novel ligands for transition metal catalysis and organocatalysts due to its sterically hindered pinacol boronate group.
• Chemical Biology Probes: Utilized in the design and synthesis of molecular probes and tags for studying biological processes, benefiting from the handle provided by the boronate ester for further functionalization.
• Custom Synthesis & Contract Manufacturing: A vital starting material for custom synthesis houses and CDMOs (Contract Development and Manufacturing Organizations) serving diverse R&D projects.

Quality Control

Our 3-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)-5-(Trifluoromethyl)Benzonitrile is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via NMR and MS, to ensure it meets the high standards required for sensitive coupling reactions. Certificates of Analysis (COA) with detailed chromatographic data are provided with each shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). The product is moisture-sensitive (hygroscopic); keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent hydrolysis of the boronate ester.
