Description

3-Ureidophenylboronic Acid Pincol Ester is a high-purity, synthetically valuable boronic acid derivative. This compound matters as a key protected intermediate in modern organic synthesis, particularly for Suzuki-Miyaura cross-coupling reactions, enabling the construction of complex biaryl structures. It is primarily needed by pharmaceutical R&D laboratories and fine chemical manufacturers for the development of active pharmaceutical ingredients (APIs) and advanced materials.

Application

• Pharmaceutical Intermediate: A crucial building block in the synthesis of novel drug candidates, especially those containing biphenyl or heterobiaryl motifs.
• Suzuki-Miyaura Cross-Coupling: Serves as a protected boronic ester reagent for palladium-catalyzed carbon-carbon bond formation under mild conditions.
• Chemical Biology & Proteomics: Used in the development of chemical probes and affinity ligands targeting proteins with serine or cysteine residues.
• Material Science Research: Employed in the creation of organic electronic materials and metal-organic frameworks (MOFs) with specific functional properties.
• Agrochemical Synthesis: Intermediate for developing new generation herbicides and fungicides with improved efficacy.
