Description

Benzoyl Chloride, 4-Amino- (9Ci) is a key aromatic amine derivative and reactive acyl chloride intermediate. This compound is essential for introducing the 4-aminobenzoyl moiety into target molecules, enabling the synthesis of complex chemical architectures. It is primarily utilized by research and development chemists and process engineers in the pharmaceutical, agrochemical, and specialty chemical industries for creating active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Critical building block for the synthesis of active pharmaceutical ingredients (APIs), particularly in antimicrobial and anti-inflammatory drug classes.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators.
• Dye and Pigment Manufacturing: Serves as a precursor for azo dyes and other high-performance colorants.
• Polymer Chemistry: Employed in the creation of specialty polyamides and polymers with specific functional groups for enhanced material properties.
• Cross-coupling Reactions: Acts as a substrate in palladium-catalyzed reactions for carbon-carbon and carbon-heteroatom bond formation.
• Peptide Modification: Used to acylate amino groups in peptides and proteins for research and bioconjugation applications.

Quality Control

Our Benzoyl Chloride, 4-Amino- (9Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets the stringent requirements of our global clientele. Certificates of Analysis (COA) documenting all critical parameters 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, well-ventilated area 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, open flames, and incompatible materials such as strong bases, alcohols, and amines.
