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. 482-05-3, Name is [1,1′-Biphenyl]-2,2′-dicarboxylic acid, molecular formula is C14H10O4, Recommanded Product: [1,1′-Biphenyl]-2,2′-dicarboxylic acid, belongs to phthalazine compound, is a common compound. In a patnet, author is Zhu, Guanxing, once mentioned the new application about 482-05-3.
Intramolecular electrophilic cyclization of a bisanthranilate afforded an angular cis-quinacridone compound, which condensed with hydrazine to give a phthalazine derivative. A [2+2+2] cyclization reaction occurred at the C-N double bond position of phthalazine when reacted with dimethyl acetylenedicarboxylate. The structures of these novel compounds were confirmed by crystallographic analysis. The phthalazine derivative decomposes back to quinacridone at ambient condition in the dark and as a solid with a half lifetime of about 22 months.
