42521-08-4 - Introduction

2. chloride is an organic compound with a chemical formula of C6H2Cl3NO. Its appearance is a colorless to pale yellow liquid with a pungent pungent odor.

The main use of this compound is as a chemical synthesis intermediate. It can be used in the synthesis of active molecules in pharmaceuticals and pesticides, such as the synthesis of pyridine compounds. In addition, it can also be used to modify polymer materials, such as to improve the performance of polyimide.

The method of preparing 2, chloride is generally obtained by reacting 2,6-dichloropyridine and formic anhydride under appropriate reaction conditions. The specific reaction conditions can be adjusted according to actual needs.

When using 2, chloride should pay attention to its safety. It is an irritating chemical, avoid contact with the skin and eyes. Appropriate protective equipment, such as lab gloves and goggles, should be used during operation. In addition, avoid contact with oxidants and combustibles during storage and transportation to prevent the risk of fire and explosion. For safety reasons, operate in a well-ventilated area and follow correct handling and disposal methods. In the event of an accident, appropriate emergency measures should be taken immediately and medical assistance should be sought.
