Polarographic determination of 1-nitro-2-aminoanthraquinone in 1,2-diaminoanthraquinone: Polarographic determination of 1-nitro-2-aminoanthraquinone in 1,2-diaminoanthraquinone. Dichenskii, V. I.; Shirokii, E. I. (USSR). Metody Anal. Kontrolya Proizvod. Khim. Prom-sti., 10, 70-1 (Russian) 1977. CODEN: MAKPDS. ISSN: 0320-0086. DOCUMENT TYPE: Journal CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) 2-Amino-1-nitroanthraquinone (I) [10262-82-5] (min. 0.5%) is detd. in 1,2-diaminoanthraquinone (II) [1758-68-5] in 10-15 min with a relative error 5-7% by polarog. at 25° (polarization rate 100 mV/min), with use of 1:1 DMF-Me2CO in 2.5 N NH4OH as ref. I shows peaks at -0.190 and -0.425 V, whereas II gives a peak at -0.490 V. The concn. of I (10-5-10-3 M) is linearly related to the diffusion current.

Chem.Several substances with their cas registry numbers 1758-68-5 and 89986-91-4 may be metioned in this study., 62(3), 526-30 (French) 1984. CODEN: CJCHAG. ISSN: 0008-4042. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Section cross-reference(s): 25, 28, 41, 75 MeCOCOMe and 1,2-diaminoanthraquinone are heated to give the methylnaphtho[2,3-f]quinoxaline-7,12-dione I and not the expected 2,3-dimethylnaphtho[2,3-f]quinoxaline-7,12-dione (II). The structure of I, detd. crystallog., had a nearly planar overall configuration which contained a bifurcated H-bond leading to 2 addnl. rings. II is the intermediate in I formation. .
