2-bromo-3-chloronitrobenzene - Introduction
It is an organic compound with the chemical formula C6H3BrClNO2. The following is a description of its nature, use, preparation and safety information:
Nature:
is a colorless to light yellow crystal with a pungent pungent odor. It has a high density, with a melting point of 38-39°C and a boiling point of 268-270°C. This compound is stable at room temperature, but decomposes under open flame or high temperature conditions.
Use:
It is mainly used as an intermediate for pesticides and dyes. It is widely used in agriculture to control pests and weeds on crops such as rice, fruit trees, vegetables and cotton. In addition, it can be used as an important reagent in organic synthesis for the synthesis of other organic compounds.
Method:
It can be synthesized by bromochlorination of 1,3-dinitrobenzene. First, under the action of nitric acid, 1,3-dinitrobenzene is nitrated to obtain 1,3-dinitro-5-nitrothionobenzene. This compound is then reacted with cuprous bromide to convert the nitro group to Bromo and chloro groups by a displacement reaction to give 2-bromo-3-chloro-5-nitrothionobenzene. Finally, the compound is subjected to alkali-catalyzed denitration reaction to obtain.
Safety Information:
is an organic compound with certain toxicity. When using and handling, strictly follow the safety practice. Contact with skin, eyes, or inhalation of high concentrations of vapors may cause irritation and injury. Therefore, you should wear protective equipment to avoid contact with the body and respiratory system. In the storage and disposal, the relevant laws and regulations should be followed. If an accident occurs carelessly, corresponding emergency measures should be taken in time and medical treatment should be taken.
