Description

Benzoyl Chloride, 4-(Butylamino)- (9Ci) is a specialized organic intermediate featuring a benzoyl chloride core functionalized with a butylamino group at the para position. This compound matters for its dual reactivity, serving as a key building block for synthesizing more complex molecules in fine chemical and pharmaceutical research. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for creating novel amides, esters, and other derivatives.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring a para-substituted benzamide or anilide structure.
• Agrochemical Synthesis: Used in the development of herbicides, fungicides, and insecticides where the butylamino-benzoyl moiety imparts specific biological activity.
• Dye and Pigment Manufacturing: Serves as an intermediate for producing azo dyes and other colorants, leveraging the amino group for chromophore development.
• Polymer Chemistry: Acts as a monomer or modifying agent for creating specialty polymers with tailored properties like UV absorption or specific reactivity.
• Organic Synthesis & Research: A versatile reagent for introducing the 4-(butylamino)benzoyl group into target molecules via nucleophilic acyl substitution reactions.
• Liquid Crystal & Electronic Material Precursor: Employed in the synthesis of advanced organic materials for display technology and semiconductors.

Quality Control

Our Benzoyl Chloride, 4-(Butylamino)- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory compliance needs.

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 properties as a strong acid/organic solvent, hygroscopic (moisture-sensitive), and highly volatile nature, it must be kept away from moisture, heat, and incompatible materials such as bases and oxidizing agents. Use appropriate corrosion-resistant storage equipment.
