Description

1-Stearylboronic Acid is a high-purity, long-chain alkylboronic acid derivative, a critical building block in modern synthetic chemistry. Its primary value lies in its role as a versatile coupling agent in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds with high selectivity and efficiency. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors, where it is used to synthesize complex organic molecules, liquid crystals, and functional polymers.

Application

• Pharmaceutical Intermediate: A key reagent in the synthesis of active pharmaceutical ingredients (APIs) via palladium-catalyzed cross-coupling reactions.
• Agrochemical Synthesis: Used in creating novel herbicides, fungicides, and insecticides with specific activity profiles.
• Advanced Material Production: Serves as a monomer or modifier in the development of liquid crystals, organic semiconductors, and specialty polymers.
• Organic Synthesis & Research: A fundamental tool in academic and industrial R&D laboratories for constructing complex organic architectures.
• Surface Modification: Can be used to functionalize surfaces and nanoparticles due to its long hydrophobic chain and reactive boronic acid group.
• Catalyst Ligand Precursor: Acts as a starting material for synthesizing specialized ligands used in homogeneous catalysis.

Quality Control

Our 1-Stearylboronic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR spectroscopy, to ensure it meets the high standards required for sensitive synthetic applications. Certificates of Analysis (COA) with detailed batch-specific results are provided to guarantee traceability and consistency.

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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
