NCCl + CH 3 CN → NCCH 2 CN + HCl. About 20,000,000 kg are produced annually (2007). Important outlets include the synthesis of thiamine, the drug triamterene and minoxidil, and the dyes disperse Yellow 90 and disperse Blue 354. [4] Malononitrile is relatively acidic, with a pK a of 11 in water. [5]
Be(NO 3) 2: beryllium nitrate: 13597–99–4 Be(NO 3) 2 •4H 2 O: beryllium nitrate tetrahydrate: 13510–48–0 Be(NO 3) 2 •3H 2 O: beryllium nitrate trihydrate: 7787–55–5 BeO: beryllium oxide: 1304–56–9 Be(OH) 2: beryllium hydroxide: 13327–32–7 BeS: beryllium sulfide: 13598–22–6 BeSO 4: beryllium sulfate: 13510–49–1 ...
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]
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 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.
Tetramethylsuccinonitrile or TMSN is an organic compound with the formula (C(CH 3) 2 CN) 2, classified as a dinitrile, and a colorless and odorless solid derived from 2,2'-azobis-isobutyronitrile, a common radical initiator in the manufacture of PVC: [(CH 3) 2 C(CN)] 2 N 2 → [(CH 3) 2 C(CN)] 2 + N 2.
