Description

4-n-Propylbenzoyl Chloride is a versatile aromatic acid chloride derivative, serving as a critical building block in advanced organic synthesis. Its primary value lies in its high reactivity as an acylating agent, enabling the efficient introduction of the 4-propylbenzoyl moiety into target molecules. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries, where it is used to develop active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a lipophilic benzoyl group.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators where the propylbenzoyl structure confers specific biological activity.
• Liquid Crystal & OLED Materials: Acts as a building block for mesogenic compounds and electron-transport materials in display and lighting technologies.
• Polymer & Resin Modification: Employed as a monomer or cross-linking agent to introduce aromatic ester functionalities into polymer chains, enhancing material properties.
• Dye & Pigment Manufacturing: Intermediate in the synthesis of complex organic dyes and pigments, contributing to color fastness and stability.
• Organic Synthesis & Research: A fundamental reagent for Friedel-Crafts acylation, amide coupling, and esterification reactions in laboratory and process-scale chemistry.

Quality Control

Our 4-n-Propylbenzoyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and Karl Fischer titration for moisture content, to ensure it meets the high standards required for sensitive synthetic applications. A comprehensive Certificate of Analysis (COA) documenting all specifications is provided with every shipment.

Storage

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