Malononitrile is an organic compound nitrile with the formula CH 2 (CN) 2. It is a colorless or white solid, although aged samples appear yellow or even brown. It is a colorless or white solid, although aged samples appear yellow or even brown.
Diaminomaleonitrile has been proposed since the 1960s as a key substance for the prebiotic synthesis of nucleobases.Photochemical rearrangement of DAMN under UV light gives 4-aminoimidazole-5-carbonitrile (AICN), which can react further to form various nucleobases.
Like most azobenzenes, Solvent Yellow 7 can be synthesized by the reaction of the phenyldiazonium salt with phenol.The optimal pH value for this azo coupling is 8.5-10. The reaction is carried out in water, since sodium chloride (or potassium chloride) formed in the reaction is soluble in water, while the product precipitates.
Sudan I (also known as CI Solvent Yellow 14 or Solvent Orange R) [1] is an organic compound typically classified as an azo dye. [2] It is an orange-red solid, used to color waxes, oils, petrol, solvents, and polishes. Historically, Sudan I used to serve as a food coloring agent, notably for curry powder and chili powder.
Tetracyanoquinodimethane (TCNQ) is an organic compound with the chemical formula (N≡C−) 2 C=C 6 H 4 =C(−C≡N) 2. It is an orange crystalline solid. This cyanocarbon, a relative of para-quinone, is an electron acceptor that is used to prepare charge transfer salts, which are of interest in molecular electronics.
2,3-xylidine, also called o-xylidine, 2,3-dimethylaniline, 2,3-xylylamine, or 2,3-dimethylphenylamine, is a liquid with melting point 2.5 °C and boiling point 222 °C, and flash point at 96 °C. Its CAS number is and its SMILES structure is Nc1cccc(C)c1C. It is used in production of mefenamic acid, dyes, and pesticides.
Methyl yellow, or C.I. 11020, is an organic compound with the formula C 6 H 5 N 2 C 6 H 4 N(CH 3) 2. It is an azo dye derived from dimethylaniline. It is a yellow solid. According to X-ray crystallography, the C 14 N 3 core of the molecule is planar. [3] It is used as a dye for plastics and may be used as a pH indicator.
Azobisisobutyronitrile (abbreviated AIBN [1]) is an organic compound with the formula [(CH 3) 2 C(CN)] 2 N 2.This white powder is soluble in alcohols and common organic solvents but is insoluble in water.
