Reference of 1698-53-9, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 1698-53-9, Name is 4,5-Dichloro-2-phenylpyridazin-3(2H)-one,introducing its new discovery.
In a process for preparing 4-amino-5-chloro-1-phenylpyridazin-6-one by reacting 4,5-dichloro-1-phenylpyridazin-6-one with aqueous ammonia in the presence of a catalyst, the catalyst used is soluble in the aqueous alkaline reaction medium but is essentially insoluble in the reaction medium which has been acidified after removal of the 4-amino-5-chloro-1-phenylpyridazin-6-one.The process of the present invention makes it possible for the catalyst to be recovered and reused in a simple manner.
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 1698-53-9, and how the biochemistry of the body works.Reference of 1698-53-9
