Description

4-Propyloxybenzoyl Chloride is a versatile and reactive organic intermediate, specifically an acid chloride derivative of 4-propyloxybenzoic acid. Its primary value lies in its role as a key acylating agent for the efficient synthesis of esters, amides, and other functionalized aromatic compounds. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors, where it is used to build complex molecular architectures.

Application

• Pharmaceutical Intermediate: Critical building block for the synthesis of active pharmaceutical ingredients (APIs), particularly those containing benzoyl or aryloxybenzamide moieties.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators that require specific aromatic ether linkages.
• Liquid Crystal Materials: Serves as a precursor in the manufacture of monomers for liquid crystal displays (LCDs) and other advanced optical materials.
• Polymer Chemistry: Acts as a monomer or modifying agent for creating specialty polyesters, polyamides, and other polymers with tailored properties.
• Organic Synthesis & Research: A valuable reagent in academic and industrial R&D labs for introducing the 4-propyloxybenzoyl group into target molecules.
• Dye and Pigment Production: Employed in the synthesis of complex organic dyes and pigments where specific solubility or chromophore properties are needed.

Quality Control

Our 4-Propyloxybenzoyl Chloride is manufactured 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 guarantee it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 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) to prevent decomposition from moisture ingress.
