COA of Formula: C18H24N6O6S4On October 31, 2020 ,《Synthesis of selenium-containing galactomannan-stabilized nanocomposites with particle size-sensitive antiradical activity》 appeared in Russian Chemical Bulletin. The author of the article were Lesnichaya, M. V.; Sapozhnikov, A. N.; Sukhov, B. G.. The article conveys some information:
Water-soluble hybrid nanocomposites were synthesized for the first time with the use of industrial crystalline selenium (gray powder selenium) activated in a hydrazine hydrate-alkali base-recovery system. The obtained nanocomposites consist of the selenium nanoparticles 13.0-24.0 nm in size stabilized by biocompatible natural polysaccharide galactomannan. The structures of the nanocomposites were characterized by a complex of physicochem. methods (X-ray diffraction anal., transmission electron microscopy, and IR spectroscopy). The pronounced antioxidant activity of the prepared nanocomposites against free radicals of 2,2-diphenyl-1-picrylhydrazyl and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt was found, and its value correlates with the particle size of selenium. The results came from multiple reactions, including the reaction of ABTS Diammonium(cas: 30931-67-0COA of Formula: C18H24N6O6S4)
ABTS Diammonium(cas: 30931-67-0) belongs to anime. To avoid the problem of multiple alkylation, methods have been devised for “blocking” substitution so that only one alkyl group is introduced. The Gabriel synthesis is one such method; it utilizes phthalimide, C6H4(CO)2NH, whose one acidic hydrogen atom has been removed upon the addition of a base such as KOH to form a salt.COA of Formula: C18H24N6O6S4
