Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Patent, the author is and a compound is mentioned, COA of Formula: C4NNa3O3S2, Sodium 3-oxido-5-sulfidoisothiazole-4-carboxylate, introducing its new discovery. COA of Formula: C4NNa3O3S2
A and Cefotetan disodium method for the preparation of intermediates (by machine translation)
The invention discloses a Cefotetan disodium method for the preparation of intermediates thereof, the commercial raw material 4 – (1-amino-3-tert-butoxy -1,3-dioxo-2-ene yl) – 1,3-dithio-azetidine-2-carboxylic acid (2) and 7-MAC (3) for a condensation reaction to make compound 4, after deprotection, salification Cefotetan disodium (1). The invention also provides the compound 2 preparation method. The conventional route of the route to avoid pollution of the environment of the use of chloride reagent, with simple process route, process cost reduction, the overall yield of product is improved, friendly characteristic of the environment, is suitable for industrial production. (by machine translation)
Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. I hope my blog about is helpful to your research. COA of Formula: C4NNa3O3S2
