Forms: 1800s– nitramine, 1900s– nitroamine.

Origin: Formed within English, by compounding. Etymons: nitro- comb. form, amine n.

Etymology: < nitro- comb. form + amine n.

Chemistry.

/ˈnʌɪtrəmiːn/, U.S.

/ˈnaɪtrəˌmin/

Origin: A borrowing from Latin, combined with an English element; modelled on a Russian lexical item. Etymons: Latin Nitraria , amine n.

Etymology: < nitr- (in scientific Latin Nitraria, genus name) + amine n., after Russian nitramin (N. Ju. Novgorodova et al. 1973, in Ximija Prirodnyx Soedinenij 196).

Chemistry.

An alkaloid which occurs naturally in several shrubs of the genus Nitraria (nitre-bushes); C₁₀H₁₉NO.

ΚΠ

1973 Chem. Abstr. 79 468/1 Nitramine, isolated from above ground parts of N[itraria] schoberi, had structure (I) as detd. by uv, ir, NMR, and mass spectroscopy.

1985 Jrnl. Nat. Products 48 903 The alkaloids (−) isonitramine..and (+) nitramine..were isolated from two species of the genus Nitraria by Russian chemists.

1988 Jrnl. Chem. Soc.: Perkin Trans. 1 1625/1 Syntheses of (+)-nitramine and of (+)- and (−)-isonitramine have been reported.
