The proposed article relates to organic chemical synthesis and the study of bis-azourea compounds, properties new N,N1 derivatives - hexamethylene bis-[(4,41-dimethyldiphenyl)-azo-2,21-diamino) ureas]. interaction [(4,41-dimethyldiphenyl)-azo-2,21-diamino)-urea] with diisocyanate gave structure bis-[(4,41-dimethyldiphenyl)-azo-2,21-diamino)urea] was established by elemental analysis, IR PMR spe...
It has been known that certain azo dyes will produce cancer of the liver. During the precancerous stages the liver appears to undergo some definite changes. The activity of these azo dye carcinogens is influenced by several dietary factors. Thus the liver can be protected partiahy from the effects of the dye by simultaneous intake of increased amounts of riboflavin (1). This conforms with the f...
4-nitro-4-[N-ethyl-N-(2-hydroxyethyl)-amino]azobenzene acrylate (C H N O ) containing an acryloxy ' 19 20 4 4 group, first 4-nitro-4-[N-ethyl-N-(2-hydroxyethyl)-amino]azobenzene was prepared by reacting 4' nitrobenzenediazonium salt with N-ethyl-N-hydroxy ethylaniline and then its acryloxyloxy derivative was synthesized in a Schoten-bauman type reaction. The characterization of the synthesized ...
In the title compound, C(11)H(8)ClN(3), the azo group adopts a trans conformation and the dihedral angle between the six-membered rings is 15.47 (8)°.
استفاده از نیمه هادی های اکسیدفلزی، برای ساخت ادوات مختلف نظیر حسگر های گاز و سلول های خورشیدی، حائز اهمیت بوده و همواره مورد مطالعه واقع شده است. در این میان برای افزایش حساسیت حسگرها از روش های مختلفی مانند افزایش دمای سطح حسگر، افزودن ناخالصی و یا اضافه کردن لایه هایی از فلزات نجیب به نیمه هادی اکسیدی و به کار گیری ساختار های نانو، استفاده می شود. کار حاضر با هدف افزایش پاسخ و انتخاب پذیری ح...

In the title compound, C(9)H(9)N(5)O(6), the azo group adopts a trans conformation and the dihedral angles between the two nitro groups and the benzene ring are 11.6 (3) and 21.3 (3)°.
The title compound, C(19)H(15)ClN(2)S, a divalent organosulfur compound belonging to the class of ortho-mercaptoazo compounds, is non-ionic in nature. The azo group in the mol-ecule is moved away from the S atom to attain the stable trans-azo configuration. Here the S atom is not electron deficient, so no intra-molecular N⋯S inter-action exists. Due to steric reasons, the mol-ecule is non-plana...
The title compound, C(12)H(8)ClN(3)O(3), in the crystalline state and in solution, exists in the azo form, as predicted by density functional theory (DFT) calculations. The mol-ecule is approximately planar [the dihedral angle between the rings is 1.83 (8)°], with the nitro group slightly twisted [13.4 (2)°] relative to the benzene ring. Translationally related mol-ecules form stacks along [010...
