《UV photostability of three 2-aminoazoles with key roles in prebiotic chemistry on the early earth》 was written by Todd, Zoe R.; Szabla, Rafal; Szostak, Jack W.; Sasselov, Dimitar D.. HPLC of Formula: 7720-39-0This research focused onUV photostability aminoazole prebiotic chem early earth. The article conveys some information:
Three related mols. in the 2-aminoazole family are potentially important for prebiotic chem.: 2-aminooxazole, 2-aminoimidazole, and 2-aminothiazole, which can provide critical functions as an intermediate in nucleotide synthesis, a nucleotide activating agent, and a selective agent, resp. Here, we examine the wavelength-dependent photodegradation of these three mols. under mid-range UV light (210-290 nm). We then assess the implications of the observed degradation rates for the proposed prebiotic roles of these compounds We find that all three 2-aminoazoles degrade under UV light, with half lives ranging from ≈7-100 h under a solar-like spectrum. 2-Aminooxazole is the least photostable, while 2-aminoimidazole is the most photostable. The relative photostabilities are consistent with the order in which these mols. would be used prebiotically: AO is used first to build nucleotides and AI is used last to activate them. In the experimental materials used by the author, we found 1H-Imidazol-2-amine(cas: 7720-39-0HPLC of Formula: 7720-39-0)
1H-Imidazol-2-amine(cas: 7720-39-0) belongs to anime. Milder oxidation, using reagents such as NaOCl, can remove four hydrogen atoms from primary amines of the type RCH2NH2 to form nitriles (R―C≡N), and oxidation with reagents such as MnO2 can remove two hydrogen atoms from secondary amines (R2CH―NHR′) to form imines (R2C=NR′). Tertiary amines can be oxidized to enamines (R2C=CHNR2) by a variety of reagents.HPLC of Formula: 7720-39-0
