Chemical engineers work across a number of sectors, processes differ within each of these areas, but chemistry and chemical engineering roles are found throughout, creation and manufacturing process of chemical products and materials. Quality Control of 2,2-Dimethoxy-2-phenylacetophenone, 24650-42-8, Name is 2,2-Dimethoxy-2-phenylacetophenone, SMILES is COC(OC)(C(=O)C1=CC=CC=C1)C1=CC=CC=C1, in an article , author is Khidre, Rizk E., once mentioned of 24650-42-8.
The reaction of 3-(1,4-dioxo-3,4-dihydrophthalazin-2(1H)-yl)-3-oxopropanenitrile 1 and salicyladehyde furnished coumarin derivatives 4 and 5. Coupling reaction of 1 with aryl diazonium chlorides and benzene-1,4-bis (diazonium) chloride gave the corresponding hydrazones 6a,b and bishydrazone 9, respectively. Hydrazones 6 underwent intramolecular cyclization upon treating with hydrazine hydrate to give 3-aminopyrazoles 7. Pyranyl phthalazine 13 was prepared from the reaction of 1 with ethyl 2-cyano-3-ethoxyacrylate 10. Enaminonitrile 14 was reacted with hydrazine hydrate/phenylhydrazine and hydroxylamine to afford the corresponding pyrazoles 16 and oxime 17. The antimicrobial evaluation revealed pyrazole derivatives 7a,b and 16a,b displayed a broad spectrum activity against most strains. 3-Aminopyrazole derivative 7b showed potent antibacterial activity against all tested microorganisms.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 24650-42-8. Quality Control of 2,2-Dimethoxy-2-phenylacetophenone.
