Description

3-Methylsulfinylphenylboronic Acid is a high-purity organoboron reagent featuring a methylsulfinyl (methyl sulfoxide) substituent. This compound is a valuable synthetic intermediate, prized for its role in facilitating Suzuki-Miyaura cross-coupling reactions to construct complex biaryl and heterobiaryl structures. It is essential for researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable, high-quality building blocks for drug discovery and fine chemical synthesis.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, particularly those containing biphenyl or heterocyclic motifs.
• Suzuki-Miyaura Cross-Coupling: Serves as a critical boronic acid partner for palladium-catalyzed carbon-carbon bond formation, enabling the creation of complex molecular architectures.
• Agrochemical Synthesis: Used in the research and development of novel herbicides, fungicides, and insecticides that require specific aryl-aryl linkages.
• Material Science Research: Employed in the development of organic electronic materials, such as those for OLEDs and organic photovoltaics, where precise molecular structure is crucial.
• Ligand and Catalyst Development: Acts as a precursor for creating specialized ligands or functionalized molecules used in catalytic systems.
• Chemical Biology Probes: Utilized in the synthesis of labeled compounds or molecular probes for biological target identification and validation studies.

Quality Control

Our 3-Methylsulfinylphenylboronic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and elemental analysis, to ensure high chemical purity and identity. We provide Certificates of Analysis (COA) with every shipment, detailing all relevant specifications. Our quality commitment ensures the material meets the stringent requirements for research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants or storing under an inert atmosphere.
