Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 50-33-9, Name is Phenylbutazone, SMILES is O=C(C1CCCC)N(C2=CC=CC=C2)N(C3=CC=CC=C3)C1=O, belongs to pyrazoles-derivatives compound. In a document, author is Xia, Xiao Li, introduce the new discover, Name: Phenylbutazone.
Highly sensitive ruthenium complex-based fluorescent probe for copper ion detection
A Ru(II) complex 1 ([Ru(bpy)(2)(L)](PF6)(2) (L = 2-(1H-pyrazol-5-yl)-1H-imidazo-[4,5-f] [1,10] phenanthroline, bpy = 2,2′-bipyridine)), which included adjacent imidazole and pyrazole moieties as responsive bidentate ligand, had been designed and synthesized as a ‘turn-off fluorescent probe for sensitively and selectively detecting Cu2+ in methanol and test strips. It displayed easy synthesis, large Stokes shift (178 nm) and long emission wavelength (633 nm). After addition of Cu2+, the probe 1 exhibited obvious fluorescence quenching (ca. 83%) and color change from red to dark. The detection limit of Cu2+ ions was as low as 1.78 x 10(-8) M, which was far lower than the permissible level of copper ion (similar to 20 mu M) in drinking water set by the EPA (Environmental Protection Agency). Moreover, the results of test strip experiments and real water sample detection experiments demonstrated the probe 1 possesses potential application of ions recognition in environment.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 50-33-9 is helpful to your research. Name: Phenylbutazone.
