2-(3-ethoxy-3-oxopropanoyl)pyridine-4-carboxylic acid - Introduction
Ethyl isonicotinoylacetate(Ethyl isonicotinoylacetate) is an organic compound with the chemical formula C10H11NO3. It is a colorless to light yellow liquid with a fragrance.
Ethyl isonicotinoylacetate is mainly used in the field of medicine, as an important intermediate for the synthesis of anti-tuberculosis drug isonicotinoylhydrazide (Isoniazid). Isonicotinoylhydrazide is a drug widely used in the treatment of tuberculosis, and Ethyl isonicotinoylacetate, as an intermediate in its synthesis, has important application value.
The preparation method of the compound is generally obtained by reacting Isonicotinic acid (Isonicotinic acid) with ethyl acetate and carrying out esterification reaction under the catalysis of alkali. Specific operating conditions and steps can refer to the organic synthesis experiment manual.
Regarding safety information, Ethyl isonicotinoylacetate is irritating and may cause irritation to the eyes, skin and respiratory tract. Therefore, it is necessary to take appropriate protective measures when handling and using, such as wearing gloves, goggles and respirators. At the same time, it should be avoided to be mixed with oxidants, strong acids and strong bases to prevent dangerous reactions. During storage, it should be sealed and kept in a cool, dry place, away from fire and flammable materials. In the event of an accident, seek professional help immediately.
