You could be based in a university, combining chemical research with teaching; in a pharmaceutical company, working on developing and trialing new drugs; helping to ensure national healthcare provision keeps pace with new discoveries. 482-05-3, Name is [1,1′-Biphenyl]-2,2′-dicarboxylic acid, SMILES is O=C(C1=CC=CC=C1C2=CC=CC=C2C(O)=O)O, belongs to phthalazine compound. In a document, author is Wang, Juxian, introduce the new discover, COA of Formula: https://www.ambeed.com/products/482-05-3.html.
A series of 3′-aminospiro[indoline-3,1′-pyrazolo[1,2-b]phthalazine]-2,5′,10′-trione derivatives have been synthesized by a one-pot three-component reaction of isatin, malononitrile or ethyl cyanoacetate and phthalhydrazide catalyzed by piperidine under ultrasound irradiation. For comparison the reactions were carried out under both conventional and ultrasonic conditions. In general, improvement in rates and yields were observed when the reactions were carried out under sonication compared with classical conditions.
