Description

4-Carboxyphenylboronic Acid is a versatile bifunctional organoboron compound featuring both a boronic acid and a carboxylic acid functional group. This dual functionality makes it a critical building block in modern synthetic chemistry, particularly for the construction of complex molecules via cross-coupling reactions. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and materials science industries developing active ingredients and advanced polymers.

Application

• Pharmaceutical Intermediate: A key precursor in Suzuki-Miyaura cross-coupling reactions for synthesizing biaryl compounds, which are core structures in numerous active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and insecticides that require specific aryl-aryl linkages.
• Material Science & OLED Development: Serves as a monomer or building block for creating conjugated polymers and organic electronic materials used in light-emitting diodes (OLEDs) and sensors.
• Bioconjugation & Probe Synthesis: Utilized in the design and synthesis of biochemical probes, diagnostic agents, and drug delivery systems due to its reactivity with diols and other functional groups.
• Ligand for Catalysis: Can be employed to create specialized ligands for transition metal catalysts used in asymmetric synthesis.
• Academic & Industrial R&D: A fundamental reagent in chemical research laboratories for method development and exploring new synthetic pathways.

Quality Control

Our 4-Carboxyphenylboronic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) with detailed specifications are provided for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
