CyanogenMod can be installed on Cyanogen OS devices. Cyanogen bromide hydrolyzes peptide bonds at the C-terminus of methionine residues. The racemic synthesis involves addition/cyclization reaction of 2-amino-1-phenylethanol with cyanogen bromide. Cyanogen bromide is a common reagent in organic synthesis. The recommended method to deactivate cyanogen bromide is with bleach. Cyanogen bromide has an extended shelflife when refrigerated. MLPC International specializes in the chemistry of carbon sulfide, cyanogen chloride and amines. Its reaction with cyanogen chloride affords malononitrile. The cyanide radical (called cyanogen) is used to measure the temperature of interstellar gas clouds. It is the trimer of cyanogen chloride. Cyanogen chloride is a molecule with the connectivity ClCN. Symmetrical 1,3,5-triazines are prepared by trimerization of certain nitriles such as cyanogen chloride or cyanimide. Another method of synthesizing cyanogen fluoride is by the fluorination of cyanogen. An M26 Gas Rocket was adapted to fire cyanogen chloride-filled warheads for these rocket launchers. Acetylene is the third-hottest natural chemical flame after dicyanoacetylene's and cyanogen at .
