Function
Isonicotinic acid is a widely used intermediate, mainly as the raw material of isoniazid (remicide), terfenadine and isonicotinate and other first-line anti-tuberculosis drugs, but also as anti-corrosive agents, plating additives, photosensitive resin stabilizer, polyvinyl chloride heat stabilizer and non-ferrous metal flotation agents.
Application
Isonicotinic acid is a widely used intermediate, mainly as a raw material for first-line anti-tuberculosis drugs such as isoniazid (ramicide), terfenadine and isonicotinate, but also as an anti-corrosive agent, electroplating additive Chemicalbook, photosensitive tree stabilizer, polyvinyl chloride heat stabilizer and non-ferrous metal flotation agents.
Isoniazid can be prepared by condensing isoniazid with hydrazine hydrate and melting for dehydration. Isoniazid has good resistance to MYCObacterium tuberculosis.
