Description

Benzoyl Chloride, 2-Chloro-3-Fluoro- (8Ci,9Ci) is a halogenated benzoyl chloride derivative, a key building block in advanced organic synthesis. Its value lies in its dual functionality as both an acylating agent and a source of a halogenated aromatic scaffold, enabling the creation of complex molecules with tailored properties. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries developing new active ingredients.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of novel active pharmaceutical ingredients (APIs), particularly those requiring a halogenated benzoyl moiety for enhanced bioactivity or metabolic stability.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides, where the fluorine and chlorine substituents can improve efficacy and environmental profile.
• Liquid Crystal & OLED Material Production: Serves as a key building block for creating halogenated aromatic cores used in electronic display and lighting technologies.
• Polymer Chemistry: Acts as a monomer or modifier in the synthesis of specialty polymers, such as polyamides or polyesters, to impart specific chemical resistance or thermal properties.
• Dye & Pigment Manufacturing: Employed in the synthesis of complex halogenated dyes and organic pigments for high-performance applications.
• Chemical Research & Development: A versatile reagent for academic and industrial R&D labs exploring new reactions and molecular architectures in medicinal and materials chemistry.

Quality Control

Our Benzoyl Chloride, 2-Chloro-3-Fluoro- (8Ci,9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high chemical purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent decomposition. Keep away from strong bases, oxidizers, and sources of moisture.
