N-Nitroso Desmethyl Dexchlorpheniramine is a nitrosamine impurity that may form during the manufacturing or storage of dexchlorpheniramine, an antihistamine. It has no therapeutic or practical use; its significance lies only in pharmaceutical safety testing, where it is monitored because nitrosamines may pose carcinogenic risks.
