Description

4-[(Diethylcarbamoyl)Amino]Benzeneboronic Acid, Pinacol Ester 98% is a high-purity, protected boronic acid derivative, also known as 4-(3-Diethylureido)Benzeneboronic Acid, Pinacol Ester, serving as a critical building block in modern synthetic chemistry. Its value lies in the pinacol ester group, which stabilizes the boronic acid functionality, making it easier to handle and store while remaining highly reactive in key cross-coupling reactions. This compound is essential for researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable, high-quality intermediates for constructing complex molecular architectures. We supply this material with a guaranteed minimum purity of 98% to ensure consistent performance in your most demanding applications.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: A key aryl boronic ester reagent for forming carbon-carbon bonds between aryl halides and the boronic acid moiety, fundamental in medicinal chemistry and material science.
• Pharmaceutical Intermediate Synthesis: Used in the research and development of active pharmaceutical ingredients (APIs), particularly for constructing biaryl structures common in many drug molecules.
• Agrochemical Product Development: Employed in the synthesis of novel herbicides, fungicides, and insecticides that require specific aryl-aryl linkages.
• Ligand and Catalyst Preparation: Serves as a precursor for synthesizing specialized ligands used in catalysis and metal-organic frameworks (MOFs).
• Organic Electronic Materials: A building block for creating conjugated polymers and small molecules used in OLEDs, organic photovoltaics, and semiconductors.
• Chemical Biology & Proteomics: Can be utilized in the development of chemical probes and affinity reagents that target specific proteins or biological pathways.
