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, 73874-95-0, name is tert-Butyl piperidin-4-ylcarbamate, introducing its new discovery. HPLC of Formula: C10H20N2O2
Compounds of formula (I): or a pharmaceutically acceptable derivative thereof, wherein R represents C1-6alkyl (optionally substituted by C1-6alkyloxy or Het) or C1-6alkyloxy; R1 and R2 independently represent hydrogen, halo or C1-6alkyl, ring A represents Het1; X represents O or NR3; R3 represents hydrogen or C1-6alkyl; ring B represents a phenyl group or Het2, either of which may be optionally substituted with one or more groups selected from halo, CN, C1-6alkyloxy, CF3, C1-6alkyl, NH2 and NO2; Het and Het1 independently represent a 5- or 6-membered saturated, partially unsaturated or aromatic heterocyclic group comprising either (a) 1 to 4 nitrogen atoms, (b) one oxygen or one sulphur atom or (c) 1 oxygen atom or 1 sulphur atoms and 1 or 2 nitrogen atoms are useful for treating anxiety, cardiovascular disease (including angina, atherosclerosis, hypertension, heart failure, edema, hypernatremia), dysmenorrhoea (primary and secondary), endometriosis, emesis (including motion sickness), intrauterine growth retardation, inflammation (including rheumatoid arthritis) mittlesmerchz, preclampsia, premature ejaculation, premature (preterm) labour and Raynaud?s disease.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 73874-95-0 is helpful to your research. HPLC of Formula: C10H20N2O2
