Description

4-(n-(3-Methylbutanoyl)Sulfamoyl)Phenylboronic Acid is a specialized organoboron compound featuring a phenylboronic acid core functionalized with a sulfamoyl linker and a 3-methylbutanoyl (isovaleryl) group. This molecular architecture makes it a valuable high-purity building block for advanced synthesis, particularly in pharmaceutical research and fine chemical manufacturing. It is primarily utilized by R&D chemists and process development scientists working on Suzuki-Miyaura cross-coupling reactions to create novel chemical entities.

Application

• Pharmaceutical Intermediate: A key synthon in the research and development of new active pharmaceutical ingredients (APIs), especially those requiring complex biaryl structures.
• Suzuki-Miyaura Cross-Coupling: Serves as a critical boron-containing coupling partner (boronic acid) for forming carbon-carbon bonds with aryl or vinyl halides, a cornerstone reaction in medicinal chemistry.
• Ligand and Catalyst Development: Used in the synthesis of novel ligands or organometallic catalysts for asymmetric synthesis and other catalytic processes.
• Material Science Research: Employed in the creation of advanced organic materials, such as organic semiconductors or metal-organic frameworks (MOFs), where precise molecular architecture is required.
• Chemical Biology Probes: Can be utilized to develop molecular probes for studying biological processes, leveraging the boronic acid group's affinity for diols.
• Custom Synthesis and Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for the production of bespoke compounds at various scales.

Quality Control

Our 4-(n-(3-Methylbutanoyl)Sulfamoyl)Phenylboronic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistent performance in sensitive applications like cross-coupling reactions. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles by HPLC, NMR, and other relevant methods is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). 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 oxidation and moisture absorption, which can compromise product integrity.
