Description

cis-Stilbeneboronic Acid Diethanolamine Ester is a specialized organoboron compound where the boronic acid functionality is protected as a diethanolamine ester. This derivative is crucial for enhancing the stability and handling characteristics of the reactive boronic acid group, particularly for moisture-sensitive applications. It serves as a valuable synthetic intermediate in cross-coupling reactions, such as the Suzuki-Miyaura reaction, enabling the construction of complex organic frameworks. This product is primarily targeted at research institutions and industrial R&D departments in the pharmaceutical, agrochemical, and advanced materials sectors.

Application

• Key intermediate in Suzuki-Miyaura cross-coupling reactions for C-C bond formation.
• Building block for the synthesis of stilbene-based pharmaceutical candidates and bioactive molecules.
• Precursor in the development of organic electronic materials and functional polymers.
• Used in agrochemical research for creating novel active ingredients.
• Facilitates ligand synthesis and catalyst development in organometallic chemistry.
• Employed in academic and industrial R&D for methodological studies and library synthesis.

Quality Control

Our cis-Stilbeneboronic Acid Diethanolamine Ester is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and elemental analysis, to ensure high chemical purity and identity. We provide full traceability and a Certificate of Analysis (COA) with every shipment, detailing all critical quality parameters. Our commitment to consistent quality supports reliable and reproducible outcomes in your synthetic processes.

Storage

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