nitronn.

Brit.

/ˈnʌɪtrɒn/, U.S.

/ˈnaɪˌtrɑn/

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

Etymology: < German Nitron (Busch & Mehrtens 1905, in Berichte der Deutsch. Chem. Ges. 38 4049) < nitro- nitro- comb. form + -on -one suffix.

Chemistry.

A yellow crystalline triazole derivative, (C₆H₅)₃C₂HN₄, which is used in gravimetric analysis as a precipitant for nitrate, perchlorate, and some other ions.
