Description

Potassium Cyclopentylmethyltrifluoroborate is an organotrifluoroborate salt, a versatile and stable reagent widely used in modern synthetic chemistry. Its primary value lies in its role as a robust coupling partner in Suzuki-Miyaura cross-coupling reactions, enabling the efficient construction of complex carbon-carbon bonds. This compound is particularly essential for researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials industries who require reliable, high-purity building blocks for drug discovery and fine chemical synthesis.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: A key reagent for introducing the cyclopentylmethyl moiety into biaryl and other complex organic frameworks.
• Pharmaceutical Intermediate Synthesis: Used in the research and development of active pharmaceutical ingredients (APIs), especially for creating novel carbon scaffolds.
• Agrochemical Manufacturing: Serves as a building block for synthesizing advanced crop protection agents and herbicides.
• Ligand and Catalyst Development: Employed in the preparation of specialized ligands and organometallic catalysts.
• Material Science Research: Useful in the synthesis of organic electronic materials and functional polymers.
• Process Chemistry & Scale-up: Valued for its stability and handling properties in kilogram-scale manufacturing processes.

Quality Control

Our Potassium Cyclopentylmethyltrifluoroborate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high chemical purity. We provide comprehensive analytical data, including NMR (1H, 11B, 13C, 19F) and HPLC analysis, to verify identity and purity. Certificates of Analysis (COA) are available for every batch upon request, documenting all critical quality attributes.

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 should be kept sealed under an inert atmosphere (argon or nitrogen) when not in use. Recommended long-term storage temperature is 2-8°C.
