Nitrosamines Impurities Testing

Our services enable you to accurately identify and measure any impurities in pharmaceutical products quickly and conveniently.

What are Nitrosamines?

Nitrosamines, or more precisely, N-nitrosamines, refer to any molecule containing a nitroso functional group.

They are chemical compounds classified as probable human carcinogens based on animal studies and have become a focus for regulatory agencies due to their potential danger. Although they are also present in some foods and drinking water supplies, their presence in medicines is nonetheless considered unacceptable.

Nitrosamine formula

Simple Nitrosamines

Some nitrosamines can be formed by the reaction of the secondary amine group contained in commonly used solvents or reagents during organic synthesis. These are usually named simple nitrosamines. The most important ones, initially controlled by FDA and Health Canada, are NDMA, NDEA, NDIPA, NEIPA, NDBA, NMPA and NMBA. However, several nitrosamines related to other solvents were added with time.

Complex Nitrosamines

Secondary amines groups contained in drug substances or their related substances can also react with nitrous acid during the organic synthesis of the API to generate nitroso adducts. These nitroso impurities are commonly named complex nitrosamines due to their specificity to each API structure and organic synthesis conditions.


As outlined on their website, health authorities (FDA, EDQM) are asking the following from Market Authorization Holders (MAH) regarding the Nitrosamines Issues.
