Mass spectrometric study of organic intermediate products and dyes

Mass spectrometric study of organic intermediate products and dyes. V. Mass spectra of 4-(arylamino)-1-aminoanthraquinones and 1,4-bis(arylamino)anthraquinones. Bezborodov, B. V.; Puchkov, V. A.Several substances like 116-75-6 may be metioned in this study. (Vses. Nauchno-Issled. Inst. Sud. Ekspertiz, USSR). Zh. Org. Khim., 14(2), 390-4 (Russian) 1978. CODEN: ZORKAE. ISSN: 0514-7492. DOCUMENT TYPE: Journal CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Section cross-reference(s): 22 In mass spectrometry of 11 anthraquinone dyes (I; R = H, Me, C6H2Me3-2,4,6, C6H4NO2-4; R1 = H, Cl, Br, OEt; R2 = H, Me; R3 = H, Me, Bu, (CH2)11Me, OMe) the predominant pathway for decompn. of the mol. There are some commonly used reagents like 116-75-6 in this article. ion was cleavage of the bond between R3R22C6H2NH and the anthraquinone nucleus. Pathways for further fragmentation were explored. The presence of halogen at R1 reduced the stability of the mol. ion, as did C6H4NO2 at R. Sufficient fragmentation occurred at 70 eV and 150 mA with sample vaporization at 200-300° to make the techniques useful as an anal. tool. ..
