Description

3-Furancarbonyl Chloride, 4-Cyano- (9Ci) is a highly reactive and versatile heterocyclic acid chloride building block. Its core value lies in its bifunctional nature, combining a reactive acyl chloride group with a cyano substituent, enabling efficient synthesis of complex molecular architectures. This compound is essential for researchers and process chemists in the pharmaceutical and agrochemical industries, where it serves as a key intermediate for the development of novel active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: A critical building block for synthesizing novel drug candidates, particularly in the development of heterocyclic compounds with potential biological activity.
• Agrochemical Synthesis: Used in the production of advanced pesticides and herbicides, where the furan and cyano groups contribute to specific modes of action.
• Material Science Precursor: Serves as a monomer or cross-linking agent in the synthesis of specialized polymers, resins, and functional organic materials.
• Ligand and Catalyst Development: Employed in the preparation of complex ligands for metal-organic frameworks (MOFs) or asymmetric catalysis.
• Fine Chemical Synthesis: A versatile reagent for introducing the 4-cyanofuran-3-carbonyl moiety into target molecules in custom synthesis and scale-up projects.
• Research & Development: A valuable tool for academic and industrial R&D in organic chemistry, medicinal chemistry, and chemical biology.

Quality Control

Every batch of 3-Furancarbonyl Chloride, 4-Cyano- (9Ci) is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure product identity, purity, and consistency for your critical synthesis work. A Certificate of Analysis (COA) detailing specifications such as assay (by HPLC or GC), identity (by IR/NMR), and impurity profiles is available for each lot upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties as a strong acid/organic solvent, hygroscopic (moisture-sensitive), and highly volatile nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool (2-8°C), dry, and well-ventilated area. Keep away from heat, open flames, and incompatible materials such as bases, alcohols, and amines.
