ChEBI: 2-Amino-5-nitrothiazole is a member of thiazoles and a C-nitro compound. | [Production Methods]
Early production of 2-Amino-5-nitrothiazole was
based on nitration of 2-acetylaminothiazole
and careful hydrolysis. Direct nitration of
2-aminothiazole gives a cleaner product and is
best achieved by adding 2-aminothiazole nitrate [57530-25-3] to concentrated sulfuric acid
at 0 – 10 ℃. This process and the nitration of o-anisidine are the only large-scale
processes based on rearrangement of an amine
nitrate, and both are potentially hazardous due
to the possibility of runaway exothermic reactions. | [Potential Exposure]
2-Amino-5-nitrothiazole is a synthetic veterinary antiprotozoal agent used since 1950 to treat farm fowl and pigeons. It is also used as an intermediate in manufacturing a group of dyes known as disperse azo dyes. It is not known to occur as a natural product. People may be exposed to 2-amino-5-nitrothiazole through contact with birds treated with the drug, releases from poultry farms, and occupational exposures in the dye industry.
