A new fluorescence method for the determination of clacium is developed. Wazo-1 reacts with calcium. forms calcium complex(Ex=297nm; Em=370nm). The interference of Mg(Ⅱ)has been studied. The reagent has better selectivity to Ca(Ⅱ) in the presence of large amount of Mg(Ⅱ). Fluorescence method has-been used for determination of microamounts of calcium in serum with new reagent Wazo-1.The results obtained are favourable.展开更多
A mild deselenenylation reaction protocol for the preparation of 3, 5-disubstituted isoxazolines and their further application to 3-methyl-5-substituted isoxazoles both in solution phase and solid phase was reported.
