Description

Potassium(Z)-2-Bromo-2-Phenylvinyltrifluoroborate is a high-value organotrifluoroborate salt, a crucial class of reagents in modern synthetic chemistry. This compound matters for its exceptional stability and utility as a robust coupling partner in transition-metal-catalyzed cross-coupling reactions, such as the Suzuki-Miyaura reaction. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials industries for constructing complex organic molecules and novel chemical entities.

Application

• Pharmaceutical Intermediate Synthesis: A key building block for constructing styrene derivatives and biphenyl scaffolds found in active pharmaceutical ingredients (APIs).
• Agrochemical Research: Used in the development of novel herbicides, fungicides, and insecticides requiring specific phenyl-substituted structures.
• Material Science: Serves as a precursor for creating functionalized organic molecules used in organic light-emitting diodes (OLEDs) and liquid crystals.
• Suzuki-Miyaura Cross-Coupling: Acts as a stable, air- and moisture-tolerant boronic acid surrogate for palladium-catalyzed carbon-carbon bond formation.
• Academic & Industrial R&D: A valuable reagent for methodology development and exploring new synthetic routes in organic chemistry laboratories.
• Fine Chemical Production: Employed in the multi-step synthesis of specialty chemicals and complex natural product analogs.

Quality Control

Our Potassium(Z)-2-Bromo-2-Phenylvinyltrifluoroborate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity for sensitive synthetic applications. Each lot is analyzed using advanced spectroscopic and chromatographic techniques. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) or as specified on the label. This material is hygroscopic (moisture-sensitive) and must be handled under an inert atmosphere (argon/nitrogen) to prevent decomposition. Keep the container tightly sealed in a desiccator when not in use.
