In an article, author is Yue, Yongshuang, once mentioned the application of 97148-39-5, SDS of cas: 97148-39-5, Name is Ammonium (Z)-2-(furan-2-yl)-2-(methoxyimino)acetate, molecular formula is C7H10N2O4, molecular weight is 186.1653, MDL number is MFCD03791040, category is benzofurans. Now introduce a scientific discovery about this category.
A Novel Fluorescent Probe Based on Spiro[chromeno[2,3-c]pyrazole-4,1 ‘-[2]benzofuran]-3 ‘-one for Detecting Copper(II) ions in Aqueous Solution
A novel fluorescent probe, DHMP {7-(dibutylamino)-3-methyl-1H,3 ‘ H-spiro[chromeno[2,3-c]pyrazole-4,1 ‘-[2]benzofuran]-3 ‘-one} was designed and synthesized by condensation of 2-[4-(dibutylamino)-2-hydroxybenzoyl]benzoic acid with 5-methyl-2,4-dihydropyrazol-3-one. The ultraviolet absorption and fluorescence emission spectra of DHMP showed a clear pH dependence and highly selective and sensitive response to copper(II) ions in aqueous medium. The detection limit of Cu2+ was estimated at 9.05 x 10(-8) M.
