Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 1194-22-5, is researched, Molecular C5H6N2O2, about Photochemical transformations of 4,6-dihydroxypyrimidine and 2-methyl-4,6-dihydroxypyrimidine isolated in low-temperature Ar, Ne and H2 matrices, the main research direction is hydroxypyrmidine photoisomerization vibrational frequency UV IR spectra.SDS of cas: 1194-22-5.
Monomers of 4,6-dihydroxypyrimidine and 2-methyl-4,6-dihydroxypyrimidine were trapped from the gas phase into low-temperature Ar, Ne and normal-H2 matrixes. Dihydroxy and oxo-hydroxy tautomers were identified. The isolated monomers were exposed to UV (285 > λ > 270 nm) radiation. For the mols. isolated in Ar and Ne matrixes, such UV excitation led to conversion of the oxo-hydroxy tautomer into three products: the dihydroxy form, the Dewar isomer and the open-ring ketene. In solid-hydrogen matrixes, UV-induced oxo-hydroxy → dihydroxy hydrogen-atom-transfer conversion did not occur; the UV-excited oxo-hydroxy form of the investigated compounds transformed only to the Dewar and open-ring ketene products.
Different reactions of this compound(6-Hydroxy-2-methylpyrimidin-4(3H)-one)SDS of cas: 1194-22-5 require different conditions, so the reaction conditions are very important.
