CHEMICAL PROPERTIES
Ethyl difluorobromoacetate is a colorless and transparent liquid. It is an important organic synthesis intermediate and is often used in the synthesis of drugs and pesticides with biological enzyme functions. In ethyl difluorobromoacetate, CF2 with strong biological activity is introduced into the compound by replacing the bromine atom. The fluorine in the α position of these compounds increases the electrophilicity of the carbonyl group, which increases the active site of biological enzymes.
