2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one (cas: 76-54-0) belongs to benzofurans derivatives. Benzofurans are compounds with a planar structure having 10 pi electrons that include the lone pair on oxygen atom, which makes it more susceptible to electrophilic attack. In nature, benzofurans have occupied an important role among the plant phenols & several pharmacologically active compounds.Product Details of 76-54-0

Rotational Diffusion Dynamics of Fluorescein Derivatives in Binary Mixtures of Solvents: An Experimental and Computational Study was written by Patil, Shivaraj A.;K.

With a view to understand the nature of solute solvent interactions, rotational reorientation times (τr) of three medium sized dipolar laser dyes viz., dichlorofluorescein (DCF), sodium fluorescein (SF) and kiton red (KR) in two binary mixtures namely, aqueous-DMSO and aqueous-1-propanol have been determined employing steady state fluorescence depolarization technique. The exptl. results are analyzed in the light of SED hydrodynamic and of Gierer and Wirtz (GW) and Dote, Kivelson and Schwartz (DKS) quasihydrodynamic models. Rotational reorientation times (τr) are plotted as function of viscosity (η) on the binary solvent mixtures An interesting hook shaped profile is observed in both the binary mixtures of solvents that is likely to shed light on solute-solvent interactions. Further, theor. study has been carried out using Gaussian 09 software. The optimized geometry, HOMO-LUMO, energy gap and mol. electron potential map (MEPM) were extracted from DFT/B3LYP 6-311g(d) basis set. The hyper conjugation or intra-mol. delocalization was estimated from NBO anal. Strong interactions were observed between nO33→Ï?C31, πN38→Ï?C12 and πO32→π*(C31- O33) with E(2) energies of 203.58, 121.89 and 39.92 kJ/mol for SF, KR and DCF. In the experiment, the researchers used many compounds, for example, 2′,7′-Dichloro-3′,6′-dihydroxy-3H-spiro[isobenzofuran-1,9′-xanthen]-3-one (cas: 76-54-0Product Details of 76-54-0).
