A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 21917-76-0, Name is 2-Methylthiazole-4-carbonitrile, molecular formula is C5H4N2S. In a Patent，once mentioned of 21917-76-0, COA of Formula: C5H4N2S
4-Cyanothiazoles are prepared by reacting beta,beta-dichloro-alpha-amino-acrylonitrile with a thioformamide in the presence of an acidic catalyst.
