Description

Benzoyl Chloride, 4-(2-Cyanoethyl)- (9Ci) CAS NO 55584-02-6 is a specialized organic intermediate featuring a benzoyl chloride core functionalized with a cyanoethyl side chain. This bifunctional structure makes it a valuable building block for synthesizing more complex molecules, particularly in advanced pharmaceutical and agrochemical research. It is primarily sought by R&D chemists and process development scientists in the fine chemical and life sciences industries for creating novel compounds with targeted biological activity.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), especially those requiring a cyanoethyl-benzamide or related pharmacophore.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides where the cyanoethyl group contributes to biological activity and molecule stability.
• Liquid Crystal & OLED Material Research: Serves as a building block for creating advanced organic electronic materials and liquid crystal compounds.
• Polymer Modification: Employed to introduce reactive benzoyl chloride groups into polymer chains for further functionalization or cross-linking.
• Dye & Pigment Intermediate: Utilized in the synthesis of specialized dyes and pigments, leveraging its aromatic and reactive chloride functionality.
• Cross-coupling Reactions: Acts as an electrophile in palladium-catalyzed and other metal-mediated coupling reactions to form carbon-carbon bonds.

Quality Control

Our Benzoyl Chloride, 4-(2-Cyanoethyl)- is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR spectroscopy, to ensure it meets the high standards required for research and process chemistry. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent derivative, 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.
