Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 618-88-2, Name is 5-Nitroisophthalic acid, molecular formula is C8H5NO6, belongs to phthalazine compound, is a common compound. In a patnet, author is Maheshwari, D. P. Loka, once mentioned the new application about 618-88-2, SDS of cas: 618-88-2.
ONE-POT SYNTHESES OF 1H-PYRAZOLO[1,2-B]PHTHALAZINE-5,10-DIONES IN MOLTEN TBAB
One-pot, four component syntheses for the preparation of 1-H Pyrazolo[1,2-b]phthalazine-5,10-diones (5a-5h) have been achieved from phthaloyl dichloride (1), hydrazine hydrate (2), benzaldehydes (3) and malononitrile (4a) or ethyl cynoacetate (4b) in molten Tetrabutylammonium Bromide as medium at 100-105 degrees C for 20-30 min by in-situ generation of HCl as a catalyst. These reactions have an easy workup, provide excellent yields, and use TBAB as the reaction medium.
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 618-88-2. The above is the message from the blog manager. SDS of cas: 618-88-2.
