Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Formula: C6H6Cl2N2. Introducing a new discovery about 34584-69-5, Name is 3,6-Dichloro-4,5-dimethylpyridazine

The hypothesis that the side effects of hydralazine, such as mutagenicity and lupus erythematosus like syndrome, might be due to the NHNH2 group prompted us to incorporate part of this moiety into pyrrole ring. Therefore, we prepared a series of N-1H-pyrrol-1-yl-3-pyridazinamines and a limited number of N-1H-pyrrol-1-yl-1-phthalazinamines by reaction of 3-hydrazinopyridazines and 1-hydrazinophthalazines with gamma-diketones. Most of these compounds, especially in the pyridazine series, showed moderate to strong antihypertensive activity in spontaneously hypertensive rats. The decrease in blood pressure generally had a slow onset after either oral or intravenous administration. N-(2,5-Dimethyl-1H-pyrrol-1-yl)-6-(4-morpholinyl)-3-pyridazinamine hydrochloride (MDL 899) showed no mutagenic activity in several tests and is now in clinical trials in patients.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C6H6Cl2N2, you can also check out more blogs about34584-69-5

17645-17-9, Name is 6-Chloro-N3-methylpyridazine-3,4-diamine, belongs to pyridazine compound, is a common compound. Formula: C5H7ClN4In an article, once mentioned the new application about 17645-17-9.

A process is described for the production of cyclohexanedimethanol by hydrogenation of a dialkyl cyclohexanedicarboxylate which comprises: (a) providing a hydrogenation zone containing a charge of a granular heterogeneous ester hydrogenation catalyst; (b) forming a vaporous feed stream of a hydrogen-containing gas,and a hydrogenatable material comprising a dialkyl cyclohexanedicarboxylate at a feed temperature which is in the range of from about 150 C. to about 350 C. and which is above the dew point of the feed stream and at a feed pressure in the range of from about 150 psia (about 10.34 bar) to about 2000 psia (about 137.90 bar), said vaporous feed stream having a known hydrogen-containing gas:dialkyl cyclohexanedicarboxylate ratio; (c) supplying the vaporous feed stream to the hydrogenation zone; (d) maintaining hydrogenation conditions in the hydrogenation zone which are effective to maintain the reaction mixture in contact with the hydrogenation catalyst above its dew point; (e) passing the vaporous feed stream through the hydrogenation zone; and (f) recovering from the hydrogenation zone a product stream containing cyclohexanedimethanol. In this process it is preferred to use dimethyl 1,4-cyclohexanedicarboxylate to produce 1,4-cyclohexanedimethanol.
