Description

Benzoyl Chloride, 4-[(Ethylamino)Carbonyl]- (9Ci) is a specialized organic intermediate featuring a benzoyl chloride core functionalized with an ethylaminocarbonyl group at the para position. This molecular architecture makes it a valuable building block for synthesizing more complex amides and active pharmaceutical ingredients (APIs). It is primarily sought after by research and development chemists and process engineers in the fine chemical and pharmaceutical sectors. The compound's reactivity as an acylating agent is key for introducing specific functional groups into target molecules.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel drug candidates, particularly those requiring a para-substituted benzamide or anilide structure.
• Agrochemical Synthesis: Used in the development of advanced herbicides and fungicides where its acyl chloride functionality enables the creation of specific amide bonds.
• Dye and Pigment Manufacturing: Acts as an intermediate for producing specialized azo dyes and organic pigments, contributing to color fastness and stability.
• Polymer Chemistry: Employed in the modification of polymers and resins, introducing reactive sites or altering material properties.
• Chemical Research: Utilized in academic and industrial R&D for exploring new organic reactions and creating libraries of compounds for screening.
• Liquid Crystal & OLED Material Development: Functions as a building block for synthesizing advanced organic electronic materials due to its planar aromatic system and modifiable functional groups.

Quality Control

Our Benzoyl Chloride, 4-[(Ethylamino)Carbonyl]- is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets exacting standards for research and industrial use. A detailed Certificate of Analysis (COA) documenting purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong acids, bases, and oxidizing agents.
