/nʌɪˈtrəʊsəmiːn/, U.S.

/naɪˈtroʊsəˌmin/

Origin: A borrowing from German. Etymon: German Nitrosamin.

Etymology: < German Nitrosamin (O. N. Witt 1875, in Berichte der Deutsch. Chem. Ges. 8 857) nitroso- nitroso- comb. form + Amin amine n.

Any of a group of yellow oily compounds having the general formula RR′N—N=O (where R, R′ represent organic radicals), which are formed by the action of nitrites or nitrogen oxides on amines.
