Description

4,4'-(1,4-Butanediyl)Bis(2-Ethyl-1,3,2-Dioxaborolane) is a high-purity, bifunctional cyclic boronic ester monomer, a key building block in advanced organic synthesis. This compound is critical for the development of novel materials and pharmaceuticals due to its ability to participate in Suzuki-Miyaura cross-coupling reactions and other boron-mediated transformations. It is primarily sought after by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs) and complex drug candidates via cross-coupling reactions.
• Polymer & Material Science: Used as a monomer or cross-linking agent in the production of specialty polymers, liquid crystals, and organic electronic materials.
• Agrochemical Synthesis: Employed in the research and development of novel herbicides, fungicides, and insecticides requiring specific boron-containing motifs.
• Organic Synthesis Reagent: Serves as a versatile reagent in academic and industrial laboratories for constructing carbon-carbon bonds and functionalized organic molecules.
• Ligand & Catalyst Development: Utilized in the preparation of novel boron-based ligands and catalysts for asymmetric synthesis and other catalytic processes.
