Description

3-Butoxyacryloyl Chloride is a highly reactive acid chloride derivative of acrylic acid, where the hydroxyl group is replaced by chlorine and the α-hydrogen is substituted with a butoxy group. This compound matters as a versatile and critical building block for introducing the 3-butoxyacryloyl moiety into target molecules, enabling the synthesis of advanced materials and fine chemicals. It is primarily needed by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediates: Key reagent in the synthesis of active pharmaceutical ingredients (APIs), particularly for constructing acrylamide-based drug candidates.
• Agrochemical Synthesis: Used to create advanced herbicides, fungicides, and insecticides by incorporating the acryloyl functional group.
• Polymer & Material Science: Serves as a monomer or cross-linking agent for producing specialty polymers with tailored properties like adhesion, weatherability, or specific reactivity.
• Liquid Crystal & OLED Materials: A crucial precursor for synthesizing photoactive and electroactive compounds used in display technologies.
• Organic Synthesis & Research: Employed in academic and industrial R&D for Michael additions, nucleophilic acyl substitutions, and other coupling reactions to create novel organic compounds.
• Surface Modifiers & Coatings: Used to functionalize surfaces or create advanced coating resins that enhance durability and performance.

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 a strong acid/organic solvent, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Keep away from heat, open flames, and incompatible materials such as bases, alcohols, and oxidizing agents.
