Description

2-Furancarbonyl Chloride, 5-(1,1-Dimethylethyl)- (9Ci) is a specialized furan-based acid chloride derivative, serving as a critical building block in advanced organic synthesis. Its value lies in its highly reactive carbonyl chloride group, which facilitates efficient acylation reactions to introduce the sterically hindered 5-tert-butyl-2-furoyl moiety into target molecules. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, where it is used to develop novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediates: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a bulky, lipophilic substituent.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides, where the furan ring contributes to biological activity.
• Polymer Chemistry: Acts as a monomer or cross-linking agent for creating specialty polymers with unique thermal or chemical resistance properties.
• Ligand and Catalyst Development: Employed in the design of novel ligands for metal catalysis and organocatalysts.
• Material Science Research: Serves as a building block for organic electronic materials, liquid crystals, and other functional organic compounds.
• Custom Synthesis and R&D: A valuable reagent for contract research organizations (CROs) and academic laboratories exploring new chemical entities.

Quality Control

Our production of 2-Furancarbonyl Chloride, 5-(1,1-Dimethylethyl)- (9Ci) adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (NMR, IR), to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its moisture-sensitive (hygroscopic) and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, alcohols, and amines.
