And the article was published in Journal of Nanoscience and Nanotechnology in 2019. Application In Synthesis of 1H-Benzo[d]imidazol-2-amine The author mentioned the following in the article:
Butane-1-soltunic acid modified starch-coated γ-Fe2O3 magnetic nanoparticles [γ-Fe2O3@starch- Bu SO3H] was easily prepared through a ring opening reaction of 1,4-butane sultone with nano- magnetic γ-Fe2O3@starch. After structural studies, using FT-IR, SEM, XRD, TGA, TEM, EDX, VSM and also pH anal. the efficiency of this reagent in the preparation of tetrahydrobenzinnidazo[2,1-b] quinazolin-1(2H)-ones and 2H-indazolo[2,1-b]phthalazine-triones was studied. Operational simple- ness, high yields, short reaction times, wide applicability and simple recyclability of the catalyst employing an external magnet are the most important advantages of this methodol. The experimental part of the paper was very detailed, including the reaction process of 1H-Benzo[d]imidazol-2-amine(cas: 934-32-7Application In Synthesis of 1H-Benzo[d]imidazol-2-amine)
1H-Benzo[d]imidazol-2-amine(cas: 934-32-7) can be used in the hydrolysis of a choline carbonate. It was also used in the synthesis of imidazo[1,2-a]benzimidazoles.Application In Synthesis of 1H-Benzo[d]imidazol-2-amine
