A new 2,6-diaminopyridine-functionalized SG1-based alkoxyamine has been synthesized and used to prepare a well-defined functional copolymer (poly(styrene-co-2-vinyl-4,4-dimethyl-5-oxazolone) – poly(S-co-VDM)) by nitroxide mediated polymerization After post-modification of the copolymer with an atom transfer radical polymerization (ATRP) ligand (N,N-dipicolyl propylamine), the macroligand was successfully used for the homogeneous ATRP of Me methacrylate (MMA) leading to a controlled polymerization process. The ATRP of the same monomer was also investigated with the macroligand being reversibly immobilized via hydrogen bonding onto thymine-functionalized silica nanoparticles. The ATRP of MMA involving the supported-catalyst was also effective leading to a good control over the polymerization as observed with the free macroligand and producing polymers with very low dispersity (<1.2). After separation of the supported catalyst by centrifugation, the amount of residual catalyst in the resulting polymers was determined In the experiment, the researchers used many compounds, for example, N-(6-Aminopyridin-2-yl)acetamide (cas: 1075-62-3Quality Control of N-(6-Aminopyridin-2-yl)acetamide).
N-(6-Aminopyridin-2-yl)acetamide (cas: 1075-62-3) belongs to pyridine derivatives. Pyridine has a conjugated system of six π electrons that are delocalized over the ring. The molecule is planar and, thus, follows the Hückel criteria for aromatic systems. Pyridine derivatives are also useful as small-molecule α-helix mimetics that inhibit protein-protein interactions, as well as functionally selective GABA ligands.Quality Control of N-(6-Aminopyridin-2-yl)acetamide
