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, 66346-83-6, name is 6-Chloropyridazine-3-carboxamide, introducing its new discovery. Computed Properties of C5H4ClN3O
Aromatic amino ethers as pain relieving agents
The present invention relates to compounds of formula (I), STR1 wherein A is an optionally substituted phenyl naphthyl, pyridyl, pyrazinyl, pyridazinyl, pyrimidyl, thienyl, thiazolyl, oxazolyl, thiadiazolyl having at least two adjacent ring carbon atoms or a bicyclic ring system, provided that the –CH(R3)N(R2)B–R1 and –OCH(R4 –)–D linking groups arm positioned in a 1,2 relationship to one another on ring carbon atoms and the ring atom positioned ortho to the –OCHR4 — linking group (and therefore in the 3-position relative to the –CHR3 NR2 — linking group) is not substituted; B is an optionally substituted ring system; D is an optionally substituted ring system; R1 is a variety of group as defined in the description; R2 is hydrogen, C1-6 alkyl, C2-6 alkenyl, C2-6 alkynyl, phenylC1-3 alkyl or 5- or 6-membered heteroarylC1-3 alkyl; R3 is hydrogen or C1-4 alkyl; R4 is hydrogen or C1-4 alkyl; and N-oxides of NR2 where chemically possible; and S-oxides of sulphur containing rings were chemically possible; and pharmaceutically acceptable salts and in vivo hydrolysable esters and amides thereof. Process for their preparation, intermediates in theirpreparation, their use as therapeutic agents and pharmaceutical compositions containing them.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 66346-83-6, and how the biochemistry of the body works.Computed Properties of C5H4ClN3O
