One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 564-25-0, Name is (4S,4aR,5S,5aR,6R,12aS)-4-(Dimethylamino)-3,5,10,12,12a-pentahydroxy-6-methyl-1,11-dioxo-1,4,4a,5,5a,6,11,12a-octahydrotetracene-2-carboxamide, formurla is C22H24N2O8. In a document, author is ADAMS, GW, introducing its new discovery. Category: isothiazole.
NEGATIVE-ION FRAGMENTATIONS OF DEPROTONATED HETEROCYCLES – THE ISOTHIAZOLE, THIAZOLE, ISOXAZOLE, AND OXAZOLE RING-SYSTEMS
The major collision-induced dissociations of deprotonated isothiazole occur from the 5-anion, while deprotonated thiazole fragments almost equally through the 2- and 5-anions. Both 5-anions fragment by a simple retro cleavage yielding HC2S- and HCN. The 5-anion of isothiazole and the 2-anion of thiazole also rearrange to the common intermediate -SCH = CHCN which decomposes by losses of H-2, HCN and H2S, There is no evidence for direct interconversion of isothiazole and thiazole anions. The spectra of deprotonated methylisothiazoles and methylthiazoles are complex, but the major fragmentations are of ring deprotonated ions and are generally analogous to the parent systems. The fragmentation behaviour of deprotonated isoxazole and oxazole is analogous to that of the isothiazole and thiazole systems.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 564-25-0 help many people in the next few years. Category: isothiazole.
