What is 4-Hydroxy-3,5-dimethoxybenzaldehyde azine?

     With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is 4-Hydroxy-3,5-dimethoxybenzaldehyde azine which has developed particularly rapidly in recent years. Do you know about 4-Hydroxy-3,5-dimethoxybenzaldehyde azine?

The official answer: hydrazone is a commonly used anti-tuberculosis drug, also known as sodium p-aminosalicylate, sodiumhydrazone, PAS-Na, white or off-white crystalline powder, odourless, sweet and salty, easily soluble in water, slightly soluble in ethanol, insoluble in acetone, almost insoluble in ether, chloroform, benzene. 2% aqueous solution pH 6.5-8. Aqueous solution is easily decarbonated to m-aminophenol. Phenol, so it should be freshly prepared when used. This product is similar in structure to p-aminobenzoic acid (PABA) and is a similar product to p-aminobenzoic acid (PABA), which inhibits the growth and reproduction of Mycobacterium tuberculosis through competitive inhibition of folic acid synthesis.

What’s the application of 4-Hydroxy-3,5-dimethoxybenzaldehyde azine?

For pulmonary and extrapulmonary tuberculosis due to Mycobacterium tuberculosis. 4-Hydroxy-3,5-dimethoxybenzaldehyde azine is effective only against Mycobacterium tuberculosis and not against non-tuberculous mycobacteria. When used alone, resistance can develop rapidly and must be combined with other anti-tuberculosis drugs. Streptomycin and isoniazid, when used in combination, can delay the development of resistance to the former two drugs in Mycobacterium tuberculosis. They are mainly used as second-line anti-tuberculosis drugs.
