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.
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.
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]
2,4,6-Tris(dimethylaminomethyl)phenol is an aromatic organic chemical that has tertiary amine and phenolic hydroxyl functionality in the same molecule. [1] The formula is C 15 H 27 N 3 O and the CAS Registry Number is 90-72-2. It is REACH registered and the European Community Number is 202-013-9. [2] [3] [4]
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 compound 2-chlorobenzalmalononitrile (also called o-chlorobenzylidene malononitrile; chemical formula: C 10 H 5 ClN 2), a cyanocarbon, is the defining component of the lachrymatory agent commonly referred to as CS gas, a tear gas which is used as a riot control agent, and is banned for use in warfare due to the 1925 Geneva Protocol.
o-Phenylenediamine (OPD) is an organic compound with the formula C 6 H 4 (NH 2) 2. This aromatic diamine is an important precursor to many heterocyclic compounds. OPD is a white compound although samples appear darker owing to oxidation by air. It is isomeric with m-phenylenediamine and p-phenylenediamine.
