Reference of 39736-29-3, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 39736-29-3, Name is Ethyl 4-amino-2-(methylthio)thiazole-5-carboxylate, molecular formula is C7H10N2O2S2. In a Article£¬once mentioned of 39736-29-3
The 2-alkylthio-4-aminothiazoles 1a-k are converted into thiazolo<4,5-d>pyrimidines 2a-f, 3, 5, 7a, and 7b.Compound 1a reacts with formamide to give 2a after two hours at 200 deg C, but after eight hours at 200 deg C 3 is the resulting product.Reactions of 1b-e with formic acid and of 1f with formic acid and water give 2a and 2c-e, whereas 2b and 2f are obtained from 1b and 1e and acetylacetone. 1f reacts with formamide to yield the expected 5.Heating of 1g, 1h, 1j, and 1k with formamide affords the 2-aminothiazolo<4,5-d>pyrimidines 7a and 7b under substitution of the alkylthio by the amino group. 2a and 2b yield with phosphoryl chloride 4a and 4b.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 39736-29-3 is helpful to your research., Reference of 39736-29-3
