Researchers are common within chemical engineering and are often tasked with creating and developing new chemical techniques, frequently combining other advanced and emerging scientific areas. Quality Control of 4-Hydrazinylbenzoic acid, 619-67-0, Name is 4-Hydrazinylbenzoic acid, SMILES is O=C(O)C1=CC=C(NN)C=C1, in an article , author is Iravani, Nasir, once mentioned of 619-67-0.
A novel heteropolyanion-based Bronsted acidic ionic liquid material [PhBS](3)PW12O40, butane mono-sulfoacid-functionalized phenanthrolinum salt of phosphortungstate catalyst (PhBS-PW), was synthesized and well characterized with FTIR, H-1 and C-13 NMR, electro-spray ionization mass spectrometry (ESI-MS), EDX and TG analysis techniques. The new prepared catalyst was used for the efficient one-pot synthesis of 2H-indazolo[2,1-b]phthalazine-trione derivatives from a three-component condensation reaction between aromatic aldehydes, dimedone, and phthalhydrazide in H2O under thermal conditions. This green approach has several advantages such as short reaction times, clean reaction profiles, and simple experimental and workup procedures. Moreover, the catalyst can be easily recovered and reused at least nine times with only slight reduction in its catalytic activity with no leaching amount of catalyst into the reaction mixture. These economical factors (time, cost, waste, etc.) for this three-component reaction hold promise for the future of organic synthesis. Graphic abstract In this work we introduced a new efficient Bronsted acidic ionic liquid (BAIL) and then its catalytic activities have been considered in the three-component synthesis of 2H-indazolo[2,1-b]phthalazine-triones via the domino Knoevenagel condensation/Michael addition/intramolecular cyclodehydration sequence in water under reflux condition.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 619-67-0. Quality Control of 4-Hydrazinylbenzoic acid.
