Ethyl 2-(ethoxymethylene)-4,4,4-trifluoro-3-oxobutanoate

Description:

Ethyl 2-(ethoxymethylene)-4,4,4-trifluoro-3-oxobutanoate, with the CAS number 571-55-1, is an organic compound characterized by its unique structure that includes a trifluoromethyl group and an ethoxymethylene moiety. This compound typically appears as a colorless to pale yellow liquid and is known for its reactivity due to the presence of both the carbonyl and the trifluoromethyl groups, which can participate in various chemical reactions, including nucleophilic additions and condensation reactions. It is often utilized in organic synthesis, particularly in the preparation of fluorinated compounds and as an intermediate in the production of pharmaceuticals and agrochemicals. The trifluoromethyl group imparts unique electronic properties, enhancing the compound's lipophilicity and metabolic stability. Safety data indicates that, like many fluorinated compounds, it should be handled with care due to potential toxicity and environmental concerns. Proper storage and handling protocols are essential to mitigate risks associated with exposure.
