Palladium-based catalysts are widely used in pharmaceutical industries, which can sometimes cause palladium contamination in pharmaceutical drug manufacture It is important to sep. quantify the different oxidation states of palladium (Pd0 and Pd2+) in pharmaceuticals as they react with scavengers differently. Although palladium sensors have been under intense investigation, oxidation state differentiators are very rare. Here, we report a simple porphyrin-coumarin conjugate, PPIX-L2, that can selectively discriminate between the oxidation states of palladium. The reaction of PPIX-L2 with Pd0 showed a 24-fold fluorescence increase of the coumarin emission, meanwhile, the presence of Pd2+ led to a 98% quenching of the porphyrin emission. Fluorescent responses of PPIX-L2 towards Pd0 and Pd2+ are specific, and its sensitivity towards both palladium species is significantly increased with a detection limit of 75 nM and 382 nM for Pd0 and Pd2+ resp. The experimental part of the paper was very detailed, including the reaction process of 3-Bromopropan-1-ol(cas: 627-18-9Safety of 3-Bromopropan-1-ol)
3-Bromopropan-1-ol(cas: 627-18-9) is used in the synthesis of fluorescent halide-sensitive quinolinium dyes, chiral, quaternary prolines through cyclization of quaternary amino acids and molten salt-polymers. It is utilized for the study of micellar media and in microemulsions based on cationic or a nonionic surfactant by reacting with phenols.Safety of 3-Bromopropan-1-ol
