Metamizole Impurity D

Biochem/physiol Actions
Antipyrine was found to be nonmutagenic when screened against Salmonella typhimurium tester strains TA100, TA98, TA97, TA102 and TA104.
Analysis Note
These secondary standards offer multi-traceability to the USP and EP primary standards, where they are available.
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.
General description
Pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
