Application

Oxidation by Fe(VI) has potential to remove N-nitrosodiumethylamine precursors, including 4-dimethylaminoantipyrine, from drinking water. 4-Dimethylaminoantipyrine is itself an effective scavenger of reactive nitrogen compounds nitric oxide and peroxynitrite, important in the inflammatory response.

Biochem/physiol Actions

Antipyrine was found to be nonmutagenic when screened against Salmonella typhimurium tester strains TA100, TA98, TA97, TA102 and TA104.
