Description

Benzoyl Chloride, 4-Amino-3-Chloro- (9Ci) is a key halogenated and aminated benzoyl chloride derivative, serving as a versatile and reactive synthetic intermediate. Its value lies in providing a bifunctional scaffold for constructing complex molecules, enabling the introduction of both benzoyl and aniline moieties in a single step. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, particularly for developing active ingredients and specialty fine chemicals.

Application

• Pharmaceutical Intermediate: A crucial building block for synthesizing novel drug candidates, especially in the development of antimicrobials, anti-inflammatory agents, and central nervous system (CNS) active compounds.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides, where its chlorinated aniline structure is incorporated into active molecules.
• Dye and Pigment Manufacturing: Serves as a precursor for azo dyes and other complex colorants, contributing to the chromophore structure.
• Polymer Chemistry: Acts as a monomer or cross-linking agent in the synthesis of specialty polymers, such as polyamides and polyimides, with enhanced thermal or mechanical properties.
• Organic Synthesis Reagent: Employed in academic and industrial R&D for Friedel-Crafts acylation and nucleophilic substitution reactions to create bespoke aromatic compounds.
• Material Science Research: Utilized in the development of organic electronic materials, liquid crystals, and metal-organic frameworks (MOFs).

Quality Control

Our Benzoyl Chloride, 4-Amino-3-Chloro- (9Ci) is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for sensitive synthetic applications. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. Keep away from incompatible materials such as strong bases, strong oxidizing agents, and alcohols.
