Description

4-(2-Carboxyvinyl)Benzeneboronic Acid is a versatile bifunctional organic building block that combines a reactive boronic acid group with a carboxylic acid moiety. This unique structure makes it a critical intermediate for the synthesis of complex molecules via cross-coupling reactions like the Suzuki-Miyaura reaction. It is primarily needed by research chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials industries for creating novel compounds and functional polymers.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing active pharmaceutical ingredients (APIs) and drug candidates, particularly those requiring biaryl or conjugated systems.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides through palladium-catalyzed cross-coupling.
• Material Science & OLEDs: Serves as a monomer or precursor for creating conjugated polymers and organic light-emitting diode (OLED) materials.
• Chemical Biology & Proteomics: Utilized in the synthesis of molecular probes, enzyme inhibitors, and bioconjugation reagents.
• Ligand & Catalyst Development: Acts as a precursor for synthesizing novel bidentate ligands used in homogeneous catalysis.
• Academic & Contract Research: Essential reagent for methodological research in organic synthesis and new reaction development.

Quality Control

Our 4-(2-Carboxyvinyl)Benzeneboronic Acid is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets the high standards required for research and process chemistry. Certificates of Analysis (COA) with detailed specifications are available upon request to support your quality assurance and regulatory documentation needs.

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 (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
