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.
The cis-configuration of the amino groups was shown in 1928 through reaction with glyoxal to give 2,3-diaminopyrazine, and the full structure was shown in 1955 to be diaminomaleonitrile, as opposed to the isomeric aminoiminosuccinonitrile (AISN). [5] It can be prepared by cyanation of aminomalonitrile. [6] [7]
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.

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.
TCNE is prepared by brominating malononitrile in the presence of potassium bromide to give the KBr-complex, and dehalogenating with copper. [1] Oxidation of TCNE with hydrogen peroxide gives the corresponding epoxide, which has unusual properties. [2] In the presence of base, TCNE reacts with malononitrile to give salts of pentacyanopropenide: [3]
Aniline Yellow is a yellow azo dye and an aromatic amine.It is a derivative of azobenzene.It has the appearance of an orange powder. Aniline Yellow was the first azo dye. it was first produced in 1861 by C. Mene.
