3,5-DICHLORO-2-PYRIDINECARBOXYLIC ACID - Introduction
3. Acid is an organic compound with the chemical formula C7H4Cl2NO2. The following is a description of some of its properties, uses, methods and safety information:
Nature:
3, acid is a colorless to yellowish crystal, soluble in some organic solvents, such as acetic acid and chloroform. Its melting point is about 117°C.
Use:
3, acid has certain uses in the field of chemical research and synthesis. It can be used as an intermediate in organic synthesis reactions, including the synthesis of drugs and pesticides. In addition, it can also be used for corrosion inhibition and rust prevention of metal surfaces.
Preparation Method:
3. The preparation method of acid can be obtained by the reaction of 3,5-dichloro -2-picolinic acid chloride and hydrated bromic acid. First, 3,5-dichloro-2-pyridinecarbonyl chloride is reacted with hydrated bromic acid in an appropriate solvent to yield the intermediate 3,5-dichloro-2-pyridinecarbonyl bromide. Then, 3,5-dichloro-2-pyridinecarbonyl bromide was converted to 3, acid by hydrolysis reaction.
Safety Information:
3, acid need to pay attention to safety when using and storing. It may cause irritation to the eyes, skin and respiratory tract and should avoid direct contact or inhalation. When in use, it is recommended to wear appropriate protective equipment, such as gloves, goggles and protective clothing.
