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. 121-66-4, Name is 5-Nitrothiazol-2-amine, molecular formula is C3H3N3O2S. In a Article，once mentioned of 121-66-4, name: 5-Nitrothiazol-2-amine
Thermal analysis of a polymorphic azo dye derived from 2-amino-5-nitrothiazole
An azo dye, derived from 2-amino-5-nitrothiazole and a substituted N,N-dimethyl aniline, was studied by various techniques. Two sets of proton signals were obtained by NMR in CDCl3 solution, suggesting that two polymorphs coexist, however, only one set of signals is observed in DMSO solution. Differential scanning calorimetry and thermogravimetric analysis were used to confirm the existence of two forms. The events registered during thermal treatment of a sample were assigned to a glass transition, recrystallization and fusion of crystalline compounds. Hot-stage microscopy was used to obtain images of the dye samples at various stages of the heating program and these observations support the interpretation of the calorimetric results.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.name: 5-Nitrothiazol-2-amine, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 121-66-4, in my other articles.
