Web15 de may. de 2003 · Nitro-substituted organic compounds pose a distinct challenge to bacterial metabolism. Exposure has been limited, because there are only a few naturally occurring nitro-substituted compounds. Nitroarenes can result from photochemical transformation of polyaromatic hydrocarbons in the atmosphere (Crawford 1993). WebAromatic nitro compounds are typically synthesized by the action of a mixture of nitric and sulfuric acids on a suitable organic molecule. Some examples of such compounds are trinitrophenol (picric acid), trinitrotoluene (TNT), and trinitroresorcinol (styphnic acid). Chloramphenicol is a rare example of a naturally occurring nitro compound.
