One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Product Details of 569-31-3, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 569-31-3, Name is 6,7-Dimethoxy-3H-1-isobenzofuranone, molecular formula is C10H10O4
Determination of Neutral Manufacturing Impurities in Heroin by Capillary Gas Chromatography with Electron Capture Detection after Reduction with Lithium Aluminum Hydride and Derivatization with Heptafluorobutyric Anhydride
Neutral byproducts associated with the manufacture of illicit heroin are many and include meconin, 4-acetoxy-3,6-dimethoxyphenanthrene, N,O6-diacetylnorcodeine, 4-acetoxy-3,6-dimethoxy-5-<2-(N-methylacetamido)ethyl>phenanthrene, N,O3,O6-triacetylnormorphine, and 4-acetoxy-3,6-dimethoxy-8-<2-(N-metnylacetamido)ethyl>phenanthrene.These N- and O-acetylated impurities, and meconin, are easily isolated from the bulk heroin matrix, after which they are subjected to reduction with lithium aluminum hydride (LiAlH4) followed by derivatization with heptafluorobutyric anhydride (HFBA) in the presence of pyridine.The resultant haptafluorobutyryl (HFB) electrophiles are detected on-column at picogram (pg) levels by using capillary column gas chromatography/electron capture detection (CC/GC/ECD) in the splitless mode.The method is applicable for the in-depth analyses of crudely processed and highly refined heroin samples.
One of the oldest and most widely used commercial enzyme inhibitors is aspirin, Product Details of 569-31-3, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 569-31-3
