By taking advantage of the intramol. charge transfer (ICT) process, we presented a novel fluorescent probe IPY-SO2 based on imidazo[1,5-α]pyridine derivative for detecting SO2-3 with a low detection limit (70 nM). Combining its favorable turn-on fluorescence feature (75-fold), rapid response (5 min), high selectivity, large Stokes shift (174 nm) and low cytotoxicity, IPY-SO2 was successfully applied to imaging SO23 in living MCF-7 cells and zebrafish. In the experiment, the researchers used many compounds, for example, Phenyl(pyridin-2-yl)methanone (cas: 91-02-1Name: Phenyl(pyridin-2-yl)methanone).
Phenyl(pyridin-2-yl)methanone (cas: 91-02-1) belongs to pyridine derivatives. Pyridine’s the lone pair does not contribute to the aromatic system but importantly influences the chemical properties of pyridine, as it easily supports bond formation via an electrophilic attack. One of the examples of pyridines is the well-known alkaloid lithoprimidine, which is an A3 adenosine receptor antagonist and N,N-dimethylaminopyridine (DMAP) analog, commonly used in organic synthesis.Name: Phenyl(pyridin-2-yl)methanone
