Laboratory analysis of NPYR
Do you want to analyze and measure NPYR (CAS: 930-55-2) in your product?
NPYR, a chemical compound classified as a hazardous substance
To begin with, 1-Nitrosopyrrolidine (NPYR) is a molecule belonging to the nitrosamine family.
Moreover, NPYR, like all nitrosamines, has been classified as a hazardous and potentially carcinogenic substance for humans by the IARC and the WHO.

Nitrosamines are also monitored by the ANSM (Agence nationale de sécurité du médicament et des produits de santé) which conducts further studies on the risks associated with the presence of nitrosamines in drugs.
