Isonicotinic acid CAS 55-22-1 Application

Isonicotinic acid is a widely used intermediate. It is mainly used as the raw material of first-line anti-tuberculosis drugs such as isoniazid (remifon), terfenadine and isonicotinate, and can also be used as anti-corrosion agent, electroplating additive, photosensitive agent. Resin stabilizer, PVC heat stabilizer and non-ferrous metal flotation agent, etc. Isoniazid can be obtained by condensing isoniazid and hydrazine hydrate, and melting and dehydrating. Isoniazid has a good antibacterial effect on Mycobacterium tuberculosis, with good curative effect, small dosage and relatively low toxicity. It can also be used for tuberculous meningitis and other extrapulmonary tuberculosis, etc. The preparations include tablets, injections, etc.
