Chemical property
White or milky white crystalline powder. Melting point is 158-160. Soluble in hot water, slightly soluble in ethanol, slightly soluble in water or chloroform, slightly soluble in ether. Bitter and slightly salty.

Uses	1.In 1959, the goods were used for the treatment of vaginal trichomoniasis. Since 1970, it has used for the intestine, extraintestinal amebiasis, and it has high efficacy, low toxicity, wide application. it has mutagenic and teratogenic effects on experimental animals.
2.It has strong antibacterial effect on most anaerobic bacteria.
3.It is used for the treatment of amebiasis, trichomoniasis and anaerobic bacteria infection.
Methods of production	It is synthetized by 2-methyl-5-nitro imidazole (see 25010) and ethylene oxide addition. 2-methyl-5-nitro imidazole dissolved in formic acid and at 30-40℃ successive adding epoxy ethane, and sulfuric acid in the middle of adding feeding. and reaction for 1 h, after that. Decompression to recycle formic acid, water solution is cooled to 10 ℃, filter. The filtrate with sodium hydroxide solution to adjust pH = 10. Set aside to cool, filtering, washing to nearly alterations into neutral, recrystallization in water. Activated carbon decolorization to get metronidazole.
