Some examples of the diverse research done by chemistry experts include discovery of new medicines and vaccines, improving understanding of environmental issues, and development of new chemical products and materials. 623-25-6, Name is α,α’-Dichloro-p-xylene, molecular formula is C8H8Cl2, Formula: https://www.ambeed.com/products/623-25-6.html, belongs to phthalazine compound, is a common compound. In a patnet, author is Abd El-Wahab, Ashraf H. F., once mentioned the new application about 623-25-6.
A series of (4-benzylphthalazin-1-ylamino) phenols 4-6 were prepared. Bromination of (4-benzylphthalazin-1-ylamino) phenol (1) with bromine afforded the bromophenol derivative 7, while condensation of the isomeric (4-benzylphthalazin-1-ylamino) phenol (2) or 7-(4-benzylphthalazin-1-ylamino)naphthalene-2-ol (3) with arylidenemalononitriles 8a-c in ethanol/piperidine solution afforded chromene derivatives 9a-c and 10a,b. Treatment of 7-(4-benzylphthalazin- 1-ylamino)-4-(p-methoxyphenyl)-4H-chromene-3-carbonitrile (9a) with triethyl orthoformate/Ac2O afforded ethoxymethyleneamino derivative 11. Condensation of 9a with DMFDMA/xylene gave chromenopyrimidine derivative 13, while treatment of 9a with Ac2O afforded the N-acetylimino derivative 14. The structures of the newly synthesized derivatives were confirmed by their elemental analysis and spectral data. The antimicrobial activities of some selected compounds were also studied and some of them were found to exhibit promising effects against Gram-positive and Gram-negative bacteria and fungi.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 623-25-6 help many people in the next few years. Formula: https://www.ambeed.com/products/623-25-6.html.
