Reference of 141-30-0, 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, and a compound is mentioned, 141-30-0, 3,6-Dichloropyridazine, introducing its new discovery.
