In an article, author is Reddy, M. Veeranaryana, once mentioned the application of 88-44-8, Name is 4-Aminotoluene-3-sulfonic acid, molecular formula is C7H9NO3S, molecular weight is 187.2163, MDL number is MFCD00007908, category is phthalazine. Now introduce a scientific discovery about this category, Recommanded Product: 4-Aminotoluene-3-sulfonic acid.
1H-Pyrazolo[1,2-6]phthalazine-5,10-dione carbonitriles and carboxylates possess a broad range of applications as active compounds in the pharmacological and biological fields. We developed an efficient and ecofriendly silica gel-supported tungstic acid (STA)-catalyzed one-pot synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione carbonitriles and carboxylates by a three-component reaction of an aldehyde, a malononitrile/ethyl cyanoacetate and a phthalhydrazide under solvent-free conditions. The major advantages of the present method are experimental simplicity, use of an inexpensive and ecofriendly reusable catalyst, good yields, and short reaction times. (C) 2014 Academie des sciences.
