Description

4-(Phenoxycarbonylamino)Benzeneboronic Acid Pinacol Ester, 95% is a high-purity boronic ester derivative, a crucial protected intermediate in modern synthetic chemistry. Its primary value lies in enabling efficient Suzuki-Miyaura cross-coupling reactions, a cornerstone methodology for constructing complex biaryl and heterobiaryl structures. This compound is essential for researchers and manufacturers in pharmaceutical development, agrochemical synthesis, and advanced materials science, where precise carbon-carbon bond formation is required.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for drugs containing biphenyl or heterobiaryl motifs.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and insecticides that require specific aryl-aryl linkages.
• Material Science Research: Employed in the development of organic electronic materials, such as organic light-emitting diodes (OLEDs) and semiconductors, where conjugated aromatic systems are critical.
• Ligand & Catalyst Development: Serves as a precursor for creating specialized ligands and catalysts used in asymmetric synthesis and other transition metal-catalyzed processes.
• Chemical Biology & Probe Synthesis: Utilized in the design and synthesis of molecular probes and bioconjugates for studying biological systems.
• Custom Synthesis & Contract Manufacturing: A vital reagent for fine chemical and custom synthesis houses serving the life sciences industry.

Quality Control

Our 4-(Phenoxycarbonylamino)Benzeneboronic Acid Pinacol Ester is produced under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets the specified 95% minimum purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your quality and regulatory requirements.

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). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect stability and reactivity. Keep away from incompatible materials.
