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.
In 1939, the International Congress for Cancer Research issued a recommendation for the banning of cancer-causing food dyes (including butter yellow) from food production. [ 5 ] [ 6 ] In 2014, dried tofu products (a.k.a. dougan 豆乾) from Taiwan were found to have been adulterated with methyl yellow, used as a coloring agent.
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.
Carbonyl cyanide m-chlorophenyl hydrazone (CCCP; also known as [(3-chlorophenyl)hydrazono]malononitrile) is a chemical inhibitor of oxidative phosphorylation. It is a nitrile , hydrazone and protonophore .
Sodium maleonitriledithiolate is the chemical compound described by the formula Na 2 S 2 C 2 (CN) 2. The name refers to the cis compound, structurally related to maleonitrile ((CH(CN)) 2). Maleonitriledithiolate is often abbreviated mnt. It is a "dithiolene", i.e. a chelating alkene-1,2-dithiolate.
The Food and Drug Administration said Wednesday it’s banning the use of Red No. 3, a synthetic dye that gives food and drinks their bright red cherry color but has been linked to cancer in animals.
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.
