Ethyl Difluoroacetate CAS 454-31-9

1. Ethyl difluoroacetate CAS 454-31-9 is a key building block for synthesizing fluorinated compounds valuable in pharmaceuticals and agrochemicals, including the preparation of pyrazolo-pyrimidine derivatives .
2. Ethyl difluoroacetate is used in medicinal chemistry to modify drug structures, enhancing efficacy and bioavailability in developing antiviral and anticancer agents .
3. Ethyl difluoroacetate is employed in the production of fluorinated polymers with superior thermal stability and chemical resistance for high-performance applications, and is utilized in acrylization oxidation and halogenating reactions of catalysts .

1. Store Ethyl difluoroacetate CAS 454-31-9 in a tightly sealed container in a cool, dry, well-ventilated place, with recommended temperatures between 0-8°C, as it is hygroscopic .
2. Keep Ethyl difluoroacetate strictly away from heat, sparks, open flames, and strong oxidizing agents, and ensure containers are grounded to prevent electrostatic discharge .
3. Handle Ethyl difluoroacetate using appropriate personal protective equipment including chemical-resistant gloves, tightly fitting safety goggles with face shield, and in a fume hood to avoid breathing vapors and contact with skin and eyes .

1. Isolate the spill area, eliminate all ignition sources, and contain liquid Ethyl difluoroacetate CAS 454-31-9 using dry inert absorbent material like sand, preventing entry into drains or waterways .
2. Collect absorbed Ethyl difluoroacetate using non-sparking, explosion-proof tools into sealed, labeled containers for disposal according to environmental regulations .
3. Personnel cleaning Ethyl difluoroacetate spills must wear full protective equipment including self-contained breathing apparatus, as vapors may form explosive concentrations and Ethyl difluoroacetate is classified for transport.

1. Ethyl difluoroacetate CAS 454-31-9 is a flammable liquid and vapor (H226, flash point 24-25°C) with GHS signal word "Danger", causing severe skin burns and serious eye damage (H314, H318) .
2. Ethyl difluoroacetate may cause respiratory irritation (H335), is harmful if swallowed (H302), and is hazardous to the aquatic environment with long-lasting effects (H412) .
3. Combustion of Ethyl difluoroacetate produces toxic fumes including carbon monoxide, carbon dioxide, and hydrogen fluoride; Ethyl difluoroacetate is incompatible with strong oxidizing agents and strong bases .
