Description

Benzoyl Chloride, 3-Cyano-4-(1-Methylethyl)- (9Ci) is a specialized benzoyl chloride derivative, distinguished by its cyano and isopropyl substituents, which serve as a versatile and reactive synthetic intermediate. Its primary value lies in enabling the efficient construction of complex molecular architectures, particularly in the synthesis of advanced pharmaceutical compounds and high-performance agrochemicals. This product is essential for R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries seeking to introduce the benzoyl moiety into target molecules under controlled conditions.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for molecules requiring a substituted benzoyl group.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides where its specific substitution pattern contributes to biological activity.
• Fine Chemical Production: Serves as a precursor for dyes, pigments, and other performance chemicals requiring a functionalized aromatic core.
• Material Science Research: Employed in the development of novel polymers, liquid crystals, and organic electronic materials as a functional monomer or cross-linking agent.
• Academic & Industrial R&D: A valuable reagent for method development and exploring new reaction pathways in organic synthesis laboratories.

Quality Control

Every batch of Benzoyl Chloride, 3-Cyano-4-(1-Methylethyl)- (9Ci) is manufactured and tested under a strict quality management system to ensure consistency and reliability for your synthetic processes. We provide comprehensive analytical data, including HPLC purity, identity confirmation (IR, NMR), and impurity profiling. A Certificate of Analysis (COA) is supplied with each shipment, detailing all relevant specifications. Our quality protocols are designed to meet the stringent requirements of cGMP and ISO standards for advanced chemical intermediates.

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, sparks, open flames, and incompatible materials such as bases, alcohols, and oxidizing agents.
