The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《The first tryptophan based turn-off chemosensor for Fe2+ ion detection》. Authors are Nagarajan, Rajendran; Vanjare, Balasaheb D.; Hwan Lee, Ki.The article about the compound:H-Trp-OMe.HClcas:7524-52-9,SMILESS:N[C@@H](CC1=CNC2=CC=CC=C12)C(OC)=O.[H]Cl).Application of 7524-52-9. Through the article, more information about this compound (cas:7524-52-9) is conveyed.
In this research work, we have designed and synthesized a novel Tryptophan-Quinoline conjugated turn-off chemosensor 4 (I) for the selective detection of Fe2+ ion with high sensitivity (3.06 μM) among 21 metal cations such as Ag+, Ca+, Cs+, Cu+, K+, Na+, NH+4, Ba2+, Ca2+, Cd2+, Co2+, Cu2+, Mn2+, Ni2+, Pb2+, Zn2+, Al3+, Au3+, Cr3+ and Fe3+ in DMF-HEPES (1 mM, pH = 7.0, 1:1, volume/volume) aqueous-organic solvent system. It showed a fluorescence quenching mechanism through the blocked PET process. The optical properties, binding mode of the metal ion with the receptor, plausible electron transfer mechanism, and its practical applications have been discussed. This work will open up a new avenue in amino acid-based Fe2+ ion sensors.
As far as I know, this compound(7524-52-9)Application of 7524-52-9 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
