Description

Potassium 2,3-Dimethylphenyltrifluoroborate is an advanced organoboron reagent, specifically an aryltrifluoroborate salt, prized for its enhanced stability and handling properties compared to traditional boronic acids. This compound serves as a crucial coupling partner in Suzuki-Miyaura cross-coupling reactions, enabling the efficient synthesis of complex biaryl structures. It is primarily utilized by research chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials industries for constructing novel molecular architectures.

Application

• Pharmaceutical Intermediate Synthesis: A key building block for constructing active pharmaceutical ingredients (APIs) and drug candidates via palladium-catalyzed cross-coupling.
• Agrochemical Research: Used in the development of new herbicides, fungicides, and insecticides requiring specific biaryl motifs.
• Material Science: Employed in the synthesis of organic electronic materials, such as those for OLEDs and conductive polymers.
• Chemical Biology & Probe Development: Facilitates the creation of labeled compounds and molecular probes for biological studies.
• Catalyst & Ligand Preparation: Serves as a precursor for synthesizing specialized ligands and catalysts used in asymmetric synthesis.
• Scale-up Process Chemistry: Its improved stability makes it suitable for kilogram-scale manufacturing processes in fine chemical production.

Quality Control

Our Potassium 2,3-Dimethylphenyltrifluoroborate is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including NMR (1H, 11B, 19F), HPLC for purity assessment, and KF titration for moisture content, to ensure it meets the high standards required for sensitive cross-coupling applications. A detailed Certificate of Analysis (COA) is provided with every shipment.

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). This material is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (argon or nitrogen) for long-term storage to maintain optimal reactivity and purity.
