Description

2-Benzofurancarbonyl Chloride, 5-Cyano- (9Ci) is a specialized benzofuran derivative that serves as a high-value synthetic intermediate. Its core value proposition lies in its dual functional groups—the acid chloride and the nitrile—which enable efficient derivatization and incorporation into complex molecular architectures. This compound is primarily needed by research and development chemists in the pharmaceutical and agrochemical industries for constructing novel active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly in kinase inhibitor and CNS-active compound research.
• Agrochemical Synthesis: Used in the development of new-generation herbicides and fungicides with specific modes of action.
• Material Science Precursor: Serves as a monomer or cross-linking agent in the production of specialty polymers and advanced organic electronic materials.
• Organic Synthesis Reagent: Employed in academic and industrial R&D for constructing complex heterocyclic frameworks via Friedel-Crafts acylation and other coupling reactions.
• Fluorescent Dye & Sensor Development: The benzofuran core is utilized in creating fluorescent probes and molecular sensors for biological and chemical detection.

Quality Control

Our 2-Benzofurancarbonyl Chloride, 5-Cyano- is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the high standards required for research and process development. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

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 hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong bases and oxidizing agents.
