An efficient and environmentally electrooxidative N-nitrosation of secondary amines using potassium/sodium nitrite as nitrosating agents has been developed. This strategy break through the innate combination of sodium nitrite and a strong acid. The reaction is compatible with the late-stage modification of pharmaceutical compounds and could be conducted in gram scale with high reaction efficiency.

drugs, antihistamines, and antibiotics also became the subject of investigation. The occurrence of NAs has shown that pharmaceutical companies and regulatory agencies did not focus on these substances in the past during drug development. In this study, we incorporated a nitrosation assay procedure into high-resolution supercritical fluid chromatography (SFC)–mass spectrometry screening to test the potential
