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.

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.

Analysis Note

These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.

Other Notes

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
