In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 35857-89-7, name is 6-Chloropyridazine-3-carbonitrile, introducing its new discovery. Application In Synthesis of 6-Chloropyridazine-3-carbonitrile
Class of spiro-linked pyrrolidine-2,5-diones
The invention provides a novel spiro-linked pyrrolidine-2,5-dione of the formula; STR1 wherein X1 and X2 each independently represent a hydrogen, a halogen atom, a lower alkyl or lower alkoxy group; Y is a methylene group, oxygen or sulfur atom; R1, R2, R3 and R4 each independently represent a hydrogen atom, a lower alkyl group or forming a benzene ring together with their adjacent carbon atoms; the base salts thereof with pharmaceutically acceptable cations, and processes for their manufactures. The compounds of formula [I] useful as aldose reductase inhibitors and as therapeutic agents for treatment of chronic diabetic complications are also disclosed.
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 35857-89-7, and how the biochemistry of the body works.Application In Synthesis of 6-Chloropyridazine-3-carbonitrile
