Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 81-48-1, Name is 1-Hydroxy-4-(p-tolylamino)anthracene-9,10-dione, molecular formula is C21H15NO3, belongs to phthalazine compound, is a common compound. In a patnet, author is Hiremath, Prashant B., once mentioned the new application about 81-48-1, Application In Synthesis of 1-Hydroxy-4-(p-tolylamino)anthracene-9,10-dione.
An efficient and rapid one-pot multicomponent synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-diones through condensation of aldehyde, malononitrile and phthalhydrazide catalyzed by agro-waste solvent catalyst-derived water extract of mango peel ash (WEMPA) under microwave irradiation is described. Further, the catalyst is prepared from agricultural waste and characterized for elemental composition by different techniques such as SEM-EDX, XRD and flame photometry. This green synthetic approach offers various advantages such as inexpensive, abundantly available source, shorter reaction time (6-8 min), good-to-excellent yield (83%-89%), simple workup and a sustainable alternative method to the existing protocols. All the synthesized compounds (4a-l) was confirmed by FT-IR,H-1-NMR,C-13-NMR and LC-MS.
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 81-48-1. The above is the message from the blog manager. Application In Synthesis of 1-Hydroxy-4-(p-tolylamino)anthracene-9,10-dione.
