《Synthesis, Structural Characterization, Enzymatic and Oxidative Polymerization of 2,6-Diaminopyridine》 was published in Journal of Fluorescence in 2020. These research results belong to Senol, Dilek. COA of Formula: C5H7N3 The article mentions the following:
Enzymic polymerization of 2,6-diaminopyridine (DAP) compound in the presence of HRP (Horse radish peroxidase) and H2O2 (hydrogen peroxide) with Poly(DAP-en) with the structures of two different types of polymers obtained by the oxidative polymerization of Poly(DAP-ox) using H2O2 in an aqueous basic environment was illuminated by 1H-NMR, 13C-NMR, FT-IR, UV-Vis spectral methods. GPC (gel permeation chromatog.), TGA (thermal gravimetric anal.), DSC (differential scanning calorimetry), CV (cyclic voltammetry), fluorescence anal. and conductivity measurements to characterize the compounds and their electronic structure were examined SEM analyzes were performed for the morphol. properties of the compounds As a result of the anal., it was observed that the polymer obtained by enzymic polymerization was better than the polymer obtained by oxidative method. It was observed that the results of the fluorescence measurements were better than Poly(DAP-en) in Poly(DAP-ox) emitting blue and green light. According to TGA anal., the first decay temperatures for poly(DAP-en) and poly(DAP-ox) were calculated as 342°C and 181°C, resp. The higher value of glass transition temperature for poly(DAP-en) confirms that the average molar mass is higher than 8650 Da for poly(DAP-en) according to GPC anal. The experimental part of the paper was very detailed, including the reaction process of 2,6-Diaminopyridine(cas: 141-86-6COA of Formula: C5H7N3)
2,6-Diaminopyridine(cas: 141-86-6) belongs to pyridine. Pyridine and its simple derivatives are stable and relatively unreactive liquids, with strong penetrating odours that are unpleasant.COA of Formula: C5H7N3
