Description

Benzoyl Chloride, 2-Chloro-5-Cyano- (9Ci) is a specialized aromatic acid chloride derivative, serving as a high-value chemical intermediate. Its core value proposition lies in its dual functional groups—the reactive benzoyl chloride moiety and the electron-withdrawing cyano substituent—which enable precise synthesis of complex molecules. This compound is essential for R&D chemists and process engineers in the pharmaceutical and agrochemical industries seeking to develop new active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel active pharmaceutical ingredients (APIs), particularly in the development of heterocyclic compounds and targeted therapies.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides, where its structure contributes to biological activity and selectivity.
• Liquid Crystal & OLED Material Precursor: Serves as a critical intermediate in the manufacture of specialty chemicals for electronic displays and organic light-emitting diodes (OLEDs).
• Polymer Modification Agent: Employed to introduce specific functional groups into polymer chains, enhancing material properties like thermal stability or adhesion.
• Dye and Pigment Manufacturing: Acts as a precursor in the synthesis of complex, high-performance dyes and organic pigments.
• Cross-Coupling Reactions: A valuable substrate in palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck) for constructing biaryl systems in fine chemical synthesis.

Quality Control

Our Benzoyl Chloride, 2-Chloro-5-Cyano- is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR, to ensure it meets the high standards required for advanced synthetic applications. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

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 hydrolysis and degradation. Keep away from heat, open flames, and incompatible materials such as strong bases, alcohols, and amines.
