A simple blue fluorescent probe to detect Hg2+ in semiaqueous environment by intramolecular charge transfer mechanism was written by Srivastava, Priyanka;Ali, Rashid;Razi, Syed S.;Shahid, Mohammad;Patnaik, Satyakam;Misra, Arvind. And the article was included in Tetrahedron Letters in 2013.Product Details of 142-64-3 This article mentions the following:
An efficient intramol. charge transfer fluorescent probe bridging benzhydryl moiety and dansyl fluorophore through piperazine unit was synthesized and characterized. The photophys. behavior of synthesized probe was analyzed in the presence of different cations in aqueous acetonitrile solution The probe showed sensitivity to detect Hg2+ ion selectively over other tested cations at 20 nM level. The probable mode of binding of Hg2+ through the nitrogen and oxygen atoms of piperazine and dansyl was established by spectral data anal. In the experiment, the researchers used many compounds, for example, Piperazine Dihydrochloride (cas: 142-64-3Product Details of 142-64-3).
Piperazine Dihydrochloride (cas: 142-64-3) belongs to piperazine derivatives. Piperazine is a fairly basic compound and is an amine solvent. Outside the body, piperazine has a remarkable power to dissolve uric acid and producing a soluble urate, but in clinical experience it has not proved equally successful. Product Details of 142-64-3
