Researchers are common within chemical engineering and are often tasked with creating and developing new chemical techniques, frequently combining other advanced and emerging scientific areas. Application In Synthesis of 5-(Ethylthio)-1H-tetrazole, 89797-68-2, Name is 5-(Ethylthio)-1H-tetrazole, SMILES is CCSC1=NN=NN1, in an article , author is Khalil, Abd El-Galil M., once mentioned of 89797-68-2.
Dibenzobarallene was used as a key intermediate for the synthesis of 2-(3-hydroxy-2-naphthoyl)-3,4,4a, 5,10,10a-hexahydro-1H-5,10-benzenobenzo[g]phthalazine-1,4-dione (2). The previous compound was coupled with the appropriate diazonium chloride to give the corresponding 4-arylazo-2-naphthol derivatives 3a-l. Also, nitration, nitrosation and bromination of compound 2 afforded the corresponding nitro, nitroso and bromo derivatives 4-6, respectively. The synthesized compounds were established and evaluated as antibacterial agents. The results showed clearly that compounds 2, 3a, 3c, 3d, 3g, 3i, 4, 5 and 6 exhibited interesting high activities compared with reference drugs. Also, these compounds were applied to polyester as disperse dyes in which their color measurement and fastness properties were evaluated.
