Description

Potassium 3-(Phenylthio)Propyltrifluoroborate is an organotrifluoroborate salt, a highly valuable class of reagents in modern synthetic chemistry. This compound serves as a stable, air- and moisture-tolerant precursor for generating nucleophilic organoboron species under mild conditions. It is primarily utilized by researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials industries for cross-coupling reactions and functional group transformations.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: A key building block for constructing C-C bonds in complex molecule synthesis, particularly for drug discovery and development.
• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and other bioactive molecules requiring specific sulfur-containing motifs.
• Agrochemical Synthesis: Employed in the creation of novel herbicides, fungicides, and insecticides where the phenylthio-propyl moiety is integral to activity.
• Material Science Research: Acts as a monomer or functionalization agent in the development of polymers and advanced organic materials.
• Ligand and Catalyst Development: Useful for preparing novel boron-containing ligands for transition metal catalysis.
• Chemical Biology Probes: Facilitates the synthesis of labeled compounds and probes for studying biological pathways.

Quality Control

Our Potassium 3-(Phenylthio)Propyltrifluoroborate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity suitable for demanding synthetic applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to relevant industry standards and can support development projects requiring specific analytical data.

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). Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent moisture absorption and degradation.
