2-Chloropyridine-3-carboxylic acid ethyl ester - Introduction
Ethyl 2-choronicotinate (2-choronicotinic acid ester) is an organic compound with the chemical formula C8H7ClNO2 and a molecular weight of 181.60g/mol. It is a colorless to light yellow liquid with a special aroma.
Ethyl 2-chloronicotinate has a wide range of applications in pharmaceutical synthesis, organic synthesis, pesticide manufacturing and other fields. It can be used as an intermediate for pesticides, for the synthesis of insecticides and herbicides. In addition, it can also be used to synthesize other organic compounds, such as pharmaceutical intermediates, dyes and fragrances.
Ethyl 2-chloronicotinate can be prepared by the reaction of nicotinic acid with chloroacetic anhydride. Nicotinic acid was first dissolved in alcohol, then a catalyst was added, chloroacetic anhydride was added dropwise to the reaction system, and the reaction was carried out for several hours. Finally, the Ethyl 2-chloronicotinate product was obtained by purification by distillation.
Safety considerations are required when using or storing Ethyl 2-chloronicotinate. It is a flammable liquid, irritating to the skin and eyes, and may cause damage to the human body. Avoid direct contact when using, wear appropriate protective gloves and goggles, and ensure a well-ventilated workplace. During storage, it should be sealed and kept in a cool, dry place, away from fire and oxidizing agents.
Summary: Ethyl 2-chloronicotinate is an organic compound with a wide range of applications and can be used in pesticide manufacturing, drug synthesis and other fields. Its preparation is obtained by reacting nicotinic acid with chloroacetic anhydride. Pay attention to safety issues during use and storage to prevent damage to humans and the environment.
