Description

3,4-Furandicarbonyldichloride(9Ci) is a highly reactive furan-based diacid chloride derivative, serving as a critical building block in advanced organic synthesis. Its value lies in its ability to efficiently introduce the versatile 3,4-furandicarboxylate moiety into target molecules, enabling the creation of novel polymers, pharmaceuticals, and functional materials. This compound is essential for R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries seeking to develop new products with enhanced properties.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those containing heterocyclic frameworks.
• Polymer Chemistry: Monomer for the production of novel polyesters, polyamides, and other high-performance polymers via condensation polymerization.
• Agrochemical Synthesis: Building block for creating new generation herbicides, fungicides, and plant growth regulators.
• Ligand and Catalyst Development: Used to synthesize complex chelating agents and organocatalysts for asymmetric synthesis.
• Material Science: Intermediate in the manufacture of organic electronic materials, dyes, and photoactive compounds.
• Cross-linking Agent: Functions as a reactive linker in the surface modification of materials and in the preparation of cross-linked polymer networks.

Quality Control

Our 3,4-Furandicarbonyldichloride(9Ci) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing including HPLC for purity, IR and NMR for structural confirmation, and tests for key impurities. We provide full traceability and Certificates of Analysis (COA) are available for all shipments to ensure compliance with your research and production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong bases, alcohols, and water.
