[f. nitroso- + -ate3.]
trans. To introduce a nitroso group into (a compound).
1920F. A. Mason tr. G. von Georgievics's Text-bk. Dye Chem. 66 The monoazo dyes derived from resorcinol can be nitrosated, but the mordant dyes obtained possess too slight tinctorial powers to be of much technical value. 1952K. Venkataraman Chem. Synthetic Dyes II. xxv. 783 Rhoduline Pure Blue 3G is prepared by nitrosating diethyl-m-phenetidine, and condensing with m-diethyl⁓aminophenol. 1973Nature 12 Oct. 326/1 The mutagenicity of MG nitrosated in human gastric juice was studied by the spot test.
Hence ˈnitrosated, ˈnitrosating ppl. adjs. Also nitroˈsatable a., capable of being converted into a nitroso compound; nitroˈsation, the process of converting into a nitroso compound.
1920F. A. Mason tr. G. von Georgievics's Text-bk. Dye Chem. 66 On nitrosation, p-nitroso derivatives are obtained where the para position is free. 1968R. O. C. Norman Princ. Org. Synthesis xi. 385 Nitrosation is limited to the very reactive nuclei of phenols and tertiary aromatic amines. 1970R. Price in K. Venkataraman Chem. Synthetic Dyes III. vii. 371 Certain of the complexes which are disclosed are derived from nitrosated o-hydroxyarylazoresorcinol dyestuffs. 1972Science 7 July 66/3 These are also the nitrosating species for secondary amines and alkylureas. Ibid. 67/3 Addition of ascorbate to certain foods containing nitrate or nitrosatable compounds might be worth considering. 1973Nature 12 Oct. 326/1 Nitrosated MG was found to be mutagenic at up to sixteen-fold dilution of the original reaction mixture. 1974Ibid. 8 Nov. 179/1 Ascorbate might be used to block in vivo formation of N-nitroso compounds from nitrosatable chemicals. |
