Description

3-Cyanobenzoyl Chloride is a versatile and reactive aromatic acid chloride derivative, serving as a critical building block in advanced organic synthesis. Its value lies in its dual functionality, where the acid chloride group enables rapid amide or ester formation, and the cyano group offers a handle for further transformation into carboxylic acids, amides, or heterocycles. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries, particularly for developing active pharmaceutical ingredients (APIs), crop protection agents, and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of various drug molecules, especially those containing benzamide or benzoic acid ester moieties.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and insecticides where the cyanobenzoyl structure is integral to biological activity.
• Liquid Crystal & Polymer Chemistry: Serves as a monomer or modifying agent for creating polymers with specific optical or thermal properties.
• Dyestuff and Pigment Manufacturing: Acts as an intermediate for producing advanced organic dyes and colorants.
• Peptide Mimetics & Bioconjugation: The reactive acid chloride is used to introduce the cyanobenzoyl group into peptides or biomolecules for research and diagnostic applications.
• Organic Synthesis Reagent: A valuable reagent for introducing the 3-cyanobenzoyl group into complex molecules under mild conditions.

Quality Control

Our 3-Cyanobenzoyl Chloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and consistency.

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) to prevent hydrolysis and degradation. Keep away from moisture, heat, and incompatible materials such as bases, alcohols, and amines.
