Description

3-Formylfuran-2-Boronic Acid is a versatile bifunctional heterocyclic building block that combines a formyl group with a boronic acid moiety on a furan scaffold. This unique structure makes it a critical intermediate for Suzuki-Miyaura cross-coupling reactions and subsequent functionalization, enabling the synthesis of complex molecular architectures. It is primarily utilized by researchers and process chemists in the pharmaceutical, agrochemical, and materials science sectors for developing novel active ingredients and functional polymers.

Application

• Pharmaceutical Intermediate: A key synthon for constructing drug candidates, particularly in the synthesis of fused heterocycles and complex bioactive molecules.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and insecticides with novel modes of action.
• Organic Light-Emitting Diodes (OLEDs): Serves as a building block for electron-transport materials and emissive layer components in display technologies.
• Ligand and Catalyst Development: Employed to create novel bidentate ligands for transition metal catalysis.
• Polymer and Material Science: Incorporated into polymer backbones via cross-coupling to create functional materials with specific electronic or mechanical properties.
• Chemical Biology Probes: Utilized in the synthesis of molecular probes for studying biological processes due to its reactive handles.

Quality Control

Our 3-Formylfuran-2-Boronic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and batch-to-batch consistency, meeting the stringent requirements of research and process chemistry. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

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 tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
