Description
4-Ethoxy-3,5-Difluorobenzoylchloride is a high-purity, multi-functional chemical intermediate essential for advanced organic synthesis. Its value lies in the strategic placement of fluorine and ethoxy groups on the benzoyl chloride core, enabling precise molecular construction. This compound is critically needed by R&D and production teams in the pharmaceutical and agrochemical sectors for developing new active ingredients and fine chemicals.
Application
- Pharmaceutical Intermediate: Key building block for synthesizing novel active pharmaceutical ingredients (APIs), particularly in fluorinated drug candidates.
- Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides where the difluoroethoxy moiety enhances biological activity and stability.
- Liquid Crystal Materials: Serves as a precursor for fluorinated liquid crystal compounds used in display technologies.
- Polymer Chemistry: Acts as a monomer or modifying agent for introducing fluorine-containing side chains into specialty polymers to alter surface properties and chemical resistance.
- Organic Synthesis Reagent: Employed in Friedel-Crafts acylation and other reactions to introduce the 4-ethoxy-3,5-difluorobenzoyl group into complex molecules.
- Material Science Research: Utilized in developing new organic electronic materials and advanced coatings.

Quality Control
Our 4-Ethoxy-3,5-Difluorobenzoylchloride is manufactured under strict quality management systems. Each batch undergoes rigorous 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 comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.
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 hygroscopic (moisture-sensitive) nature and reactivity as an acid chloride, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition from moisture absorption. Keep away from strong bases and oxidizing agents.
