4-Bromocrotonic acid ethyl ester - Introduction
Ethyl 4-bromocrotonate(Ethyl 4-bromocrotonate) is an organic compound with the chemical formula C6H9BrO2. It is a colorless liquid with a special smell.
Ethyl 4-bromocrotonate is an important organic synthesis intermediate, mainly used in the synthesis of other organic compounds. It can be used in the preparation of drugs, pesticides and other organic synthesis reaction catalyst.
The common method for preparing Ethyl 4-bromocrotonate is to react ethyl crotonate with hydrogen bromide. The reaction conditions are generally at room temperature, the reactants are mixed in certain proportions, and the reaction is stirred for a period of time. After completion of the reaction, the product is obtained by separation and purification methods such as distillation.
Pay attention to safety when using and storing Ethyl 4-bromocrotonate. It is irritating and can cause damage to the eyes, respiratory system and skin. Therefore, wear appropriate protective equipment, such as gloves, goggles and protective masks, during contact and operation, and ensure that the operation is carried out in a well-ventilated environment. In addition, it is also flammable and needs to be kept away from fire and high temperatures. When storing, the container needs to be sealed and stored in a cool, dry place, away from fire and oxidizing agents.
