Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 145100-51-2, Name is 2-[N,N-Bis(Trifluoromethylsulphonyl)amino]-5-chloropyridine, molecular formula is , belongs to pyridine-derivatives compound. In a document, author is Wang Shuxin, Safety of 2-[N,N-Bis(Trifluoromethylsulphonyl)amino]-5-chloropyridine.
A Sensitive Fluorescent Turn-on Probe NapP-deap Based on Naphthalimide Derivative to Detect Hg(II) Ions in HEPES Buffer Solution and Living Cells
A highly sensitive fluorescent turn-on probe NapP-deap based on naphthalimide derivative was developed that bound Hg2+ ions rapidly in the N-2-hydroxyethylpiperazine-N-ethane-sulphonic acid(HEPES) buffer solution via photo-induced electron transfer(PET) being inhibited mechanism. The titration experiment displayed that the emission intensity of NapP-deap at 540 nm was almost linearly increased by about 3-fold. The Job’s plot showed a stoichiometry factor of 1:1 of the ligand-to-metal ratio. The detection limit of fluorescent probe was calculated to be 6.2×10(-9) mol/L. H-1 NMR studies could confirm that one Hg2+ ion was bound by the N atoms(a, b) of piperazine or the N atom(c) of pyridine. The fluorescent probe could be used for the detection of Hg2+ ions in living cells.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 145100-51-2, in my other articles.
