Description

3-(Trifluoromethylthio)-Benzeneboronic Acid is a high-value organoboron building block featuring a unique trifluoromethylthio (-SCF₃) substituent. This compound is essential for advanced cross-coupling reactions, particularly in the synthesis of complex molecules where the introduction of the highly lipophilic and electron-withdrawing SCF₃ group is required. It is a critical intermediate for researchers and manufacturers in the pharmaceutical and agrochemical industries developing new active ingredients with enhanced metabolic stability and bioavailability.

Application

• Pharmaceutical Intermediate: Key building block in Suzuki-Miyaura cross-coupling reactions for the synthesis of novel drug candidates, especially those targeting CNS disorders and oncology.
• Agrochemical Synthesis: Used in the research and development of next-generation herbicides, fungicides, and insecticides that leverage the properties of the SCF₃ group for improved efficacy.
• Material Science Research: Serves as a precursor for creating advanced organic electronic materials, such as novel ligands for catalysts or monomers for specialty polymers.
• Chemical Biology & Probe Development: Employed in the design of molecular probes and bio-conjugation reagents for studying biological processes and protein interactions.
• Custom Synthesis & Contract Manufacturing: Supplied to CROs and CDMOs for use in client-directed synthesis projects requiring this specific boronic acid derivative.

Quality Control

Our 3-(Trifluoromethylthio)-Benzeneboronic Acid is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets the high standards required for sensitive cross-coupling chemistry. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and when dispensing to prevent degradation.
