Description

Borate(1-), Trifluoro(4-Pentenyl)-, Potassium, (T-4)- is a specialized organoboron potassium salt with a unique pentenyl side chain and trifluoroborate anion. This compound is valued for its utility as a stable, air- and moisture-tolerant reagent in advanced synthetic chemistry, particularly in cross-coupling reactions. It is primarily needed by research and development laboratories, pharmaceutical intermediates manufacturers, and fine chemical producers working on complex molecule synthesis.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: Acts as a stable, easy-to-handle organoboron reagent for constructing carbon-carbon bonds in pharmaceutical and agrochemical synthesis.
• Intermediate for Active Pharmaceutical Ingredients (APIs): Used in the multi-step synthesis of complex drug molecules requiring specific boron-containing building blocks.
• Material Science Research: Serves as a precursor for developing novel organic electronic materials or polymers with tailored properties.
• Ligand and Catalyst Development: Employed in the preparation of new catalytic systems or as a model substrate in methodological studies.
• Fine Chemical Synthesis: Utilized for the precise introduction of functionalized pentenyl groups into target molecules in specialty chemical production.

Quality Control

Our Borate(1-), Trifluoro(4-Pentenyl)-, Potassium, (T-4)- is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including NMR (1H, 11B, 19F) and HPLC analysis, to ensure high chemical purity and identity. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee batch-to-batch consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Recommended long-term storage temperature is 2-8°C (refrigerated).
