Application of 141-30-0, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 141-30-0, molcular formula is C4H2Cl2N2, introducing its new discovery.
VASOCONSTRICTIVE DIHYDROBENZOPYRAN DERIVATIVES
The present invention is concerned with compounds of formula STR1 the pharmaceutically acceptable acid addition salts thereof, and the stereochemically isomeric forms thereof, wherein R 1 is hydrogen or C. sub.1-6 alkyl; R 2 is hydrogen or C 1-6 alkyl; R. sup.3 is hydrogen or C 1-6 alkyl; R 4 is hydrogen, halo, C 1-6 alkyl, hydroxy, C 1-6 alkyloxy, aryloxy or arylmethoxy; R 5 and R 6 designate R 5a and R 6a wherein R 5a and R 6a taken together form a bivalent radical; or R 5 and R 6 can designate R. sup.5b and R. sup.6b wherein R 5b is hydrogen and R 6b is a heterocycle or an optionally substituted alkenyl or alkynyl group; or R. sup.5 and R 6 designate R 5c and R 6c, wherein R. sup.5c and R 6c are hydrogen, halo, C 1-6 alkyl, C 3-6 alkenyl, C 3-6 alkynyl, hydroxy, C 1-6 alkyloxy, cyano, aminoC. sub.1-6 alkyl, carboxyl, C 1-6 alkyloxycarbonyl, nitro, amino, aminocarbonyl, C 1-6 alkylcarbonylamino, or mono-di(C 1-6 alkyl)amino; Q is a heterocyclic ring containing at least one nitrogen atom or a radical of formula STR2 pharmaceutical compositions, preparations and use as a medicine are also described.
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 141-30-0 is helpful to your research. Application of 141-30-0
