Description

Benzoyl Chloride is a versatile and highly reactive organic acid chloride, serving as a fundamental building block in industrial organic synthesis. Its primary value lies in its ability to efficiently introduce the benzoyl group into target molecules, making it indispensable for the production of a wide range of derivatives. This compound is critically needed by manufacturers in the pharmaceutical, agrochemical, polymer, and specialty chemical industries for synthesizing peroxides, dyes, fragrances, and resins.

Application

• Pharmaceutical Intermediates: Key starting material for the synthesis of benzoyl peroxide (a topical antiseptic), benzophenone derivatives (UV absorbers), and various active pharmaceutical ingredients (APIs).
• Agrochemical Production: Used in the manufacture of herbicides, fungicides, and plant growth regulators.
• Polymer & Resin Initiator: Essential precursor for benzoyl peroxide, a widely used initiator in the polymerization of plastics like polystyrene and PVC.
• Dye and Pigment Synthesis: Employed in the production of triarylmethane dyes and other colorants.
• Fragrance and Flavor Compounds: Intermediate for synthesizing benzaldehyde, benzoates, and other aroma chemicals.
• Organic Synthesis Reagent: A common reagent for Friedel-Crafts acylation and esterification reactions in research and fine chemical production.

Quality Control

Our Benzoyl Chloride is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and impurity profiles. Certificates of Analysis (COA) detailing results from GC, titration, and other relevant methods are provided to guarantee consistent quality and traceability for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, ignition sources, and incompatible materials such as strong bases, alcohols, and amines. Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent moisture absorption and decomposition. Recommended storage temperature: 2-8°C for extended stability.
