Electric Literature of 4100-80-5, 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, 4100-80-5, 3-Methyldihydrofuran-2,5-dione, introducing its new discovery.
An aromatic deviative of butyric acid has the formula STR1 wherein R1, R2, R3 and R4, each independently, represent hydrogen or alkyl, with at least two of R1 -R4 being other than hydrogen, A represents methylene or dimethylene; when A represents dimethylene, R1 and R3 can together form methylene or dimethylene, R5 and R6 represent hydrogen, halogen, alkyl, alkoxy or hydroxy, R’ represents hydrogen, hydroxy, alkoxy or acyloxy, R” represents hydrogen or alkoxy, or R’ and R” taken together form oxo or hydroxyimino, R8 represents hydrogen or alkyl and R7 represents –OR9 or STR2 R9 represents hydrogen, alkyl, monohydroxyalkyl, polyhydroxyalkyl, aryl or aralkyl, optionally substituted, a sugar residue, carboxyalkyl or alkoxycarbonylalkyl, r’ and r” represent hydrogen, alkyl, monohydroxyalkyl optionally interrupted by a heteroatom, polyhydroxyalkyl, aryl or benzyl optionally substituted, amino acid residue or aminated sugar residue, or r’ and r” taken together form a heterocycle, optionally substituted by a C1 -C3 hydroxyalkyl, and to the salts of the compounds of formula I, to their optical isomers as well as the tautomers of the compounds of formula I. These aromatic derivatives of butyric acid are useful in human and veterinary medicines as well as in cosmetic compositions.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Electric Literature of 4100-80-5. In my other articles, you can also check out more blogs about 4100-80-5
