Description

Potassium (2-Methylthiophenyl)Trifluoroborate is a high-purity organotrifluoroborate salt, a versatile and stable intermediate for advanced organic synthesis. Its primary value lies in enabling efficient Suzuki-Miyaura cross-coupling reactions, a cornerstone methodology for constructing complex biaryl and heteroaryl structures. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and materials science industries who require reliable, high-quality building blocks for drug discovery and specialty chemical development.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, particularly those containing thiophene or biaryl motifs.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and insecticides that require specific aryl-aryl linkages.
• Material Science Research: Employed in the development of organic electronic materials, such as organic light-emitting diodes (OLEDs) and semiconductors, where precise molecular architecture is critical.
• Ligand and Catalyst Development: Serves as a precursor or intermediate in the creation of novel ligands and organometallic catalysts for transition metal-catalyzed reactions.
• Chemical Biology Probes: Utilized in the synthesis of labeled compounds and molecular probes for biochemical and diagnostic applications.
• Custom Synthesis and Contract Manufacturing: A reliable reagent for custom synthesis houses and CROs/CMOs performing complex, multi-step organic syntheses for clients.

Quality Control

Our Potassium (2-Methylthiophenyl)Trifluoroborate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (1H, 11B, 19F) and HPLC analysis, to ensure high chemical purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect product stability and performance. Keep away from incompatible materials.
