Description

Methyl 3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-5-(trifluoromethoxy)benzoate is a high-value, multi-functional chemical building block essential for modern synthetic chemistry. Its core value lies in the combination of a protected boronic ester group and a trifluoromethoxy-substituted aromatic ring, enabling precise cross-coupling reactions and the introduction of desirable physicochemical properties into target molecules. This compound is primarily needed by research scientists and process chemists in the pharmaceutical, agrochemical, and advanced materials sectors for the development of novel active ingredients and functional polymers.

Application

• Pharmaceutical Intermediate: A key precursor in Suzuki-Miyaura cross-coupling reactions for constructing complex biaryl scaffolds found in drug candidates, particularly those targeting CNS disorders and inflammatory diseases.
• Agrochemical Synthesis: Used to incorporate the trifluoromethoxy group into herbicides, fungicides, and insecticides, enhancing their lipophilicity, metabolic stability, and biological activity.
• Material Science Research: Serves as a monomer or functionalization agent in the synthesis of specialty polymers, liquid crystals, and organic electronic materials (OLEDs, OFETs) due to its aromatic and halogenated structure.
• Chemical Biology & Probe Development: Employed in creating tagged molecules and activity-based probes for studying biological pathways and enzyme functions.
• Custom Synthesis & Contract Manufacturing: A critical starting material for custom synthesis houses and CDMOs (Contract Development and Manufacturing Organizations) producing bespoke compounds for client R&D programs.

Quality Control

Our Methyl 3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-5-(trifluoromethoxy)benzoate is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (NMR, IR, MS), to ensure compliance with exacting customer specifications. Certificates of Analysis (COA) detailing batch-specific results are provided and can be tailored to meet the requirements of cGMP, ICH Q7, and other relevant pharmaceutical or research guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). The container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to maximize shelf-life stability, as the boronic ester moiety may be sensitive to prolonged exposure to moisture.
