Description

2,2-Diphenyl-1-Ethylboronic Acid Diethanolamine Ester is a specialized organoboron compound, valued for its enhanced stability and solubility profile compared to its parent boronic acid. This diethanolamine ester derivative is a crucial intermediate in advanced organic synthesis, particularly in cross-coupling reactions. It is primarily sought after by R&D chemists and process development scientists in the pharmaceutical and agrochemical industries for constructing complex molecular architectures.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: Acts as a key boron-containing coupling partner for the synthesis of biaryl and heterobiaryl structures, which are common motifs in active pharmaceutical ingredients (APIs).
• Pharmaceutical Intermediate Synthesis: Used in the research and development of novel drug candidates, including kinase inhibitors and other small molecule therapeutics.
• Agrochemical Research: Employed in creating new active ingredients for crop protection products, leveraging its ability to form carbon-carbon bonds under mild conditions.
• Material Science & OLED Development: Serves as a building block for organic electronic materials, such as charge-transport layers or emissive materials in organic light-emitting diodes (OLEDs).
• Ligand & Catalyst Preparation: Utilized in the synthesis of novel ligands for transition metal catalysts or as a precursor for other functionalized boron reagents.

Quality Control

Our 2,2-Diphenyl-1-Ethylboronic Acid Diethanolamine Ester is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and elemental analysis, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications 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 room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to maintain optimal purity and reactivity.
