Description

Potassium (3-Methylthiophenyl)Trifluoroborate is a versatile organotrifluoroborate salt, a crucial building block in modern synthetic chemistry. Its value lies in its enhanced stability and handling characteristics compared to traditional boronic acids, making it an indispensable reagent for robust cross-coupling reactions. This compound is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials industries for constructing complex molecular architectures.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: A key reagent for forming carbon-carbon bonds between aryl/heteroaryl groups, essential for synthesizing complex organic molecules.
• Pharmaceutical Intermediate Synthesis: Used in the research and production of active pharmaceutical ingredients (APIs) and drug candidates, particularly those containing biaryl or heterobiaryl motifs.
• Agrochemical Development: Employed in creating novel herbicides, fungicides, and insecticides that require specific aryl-aryl linkages.
• Material Science & OLED Research: Facilitates the synthesis of conjugated organic molecules for use in organic light-emitting diodes (OLEDs) and other electronic materials.
• Ligand and Catalyst Preparation: Serves as a precursor for synthesizing specialized ligands and catalysts used in asymmetric synthesis and other catalytic processes.
• Chemical Biology & Probe Development: Useful for labeling and modifying biomolecules in research applications due to its selective reactivity profile.

Quality Control

Our Potassium (3-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 consistent performance in sensitive coupling reactions. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment.

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 material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) when possible to maintain long-term stability.
