The presence of pharmaceuticals and personal care products (PPCPs) in aquatic systems has raised concern about their potential adverse effects on aquatic organisms. Considering the fact that the physiol./biol. effects of PPCPs are triggered when their concentrations in the organism exceeds the resp. threshold values, it is important to understand the bioconcentration and toxicokinetics of PPCPs in aquatic organisms. In the present study, we developed a convenient anal. method for the determination of 65 pharmaceuticals and 7 personal care products (log Kow = 0.14-6.04) in plasma and whole-body tissues of fish. The anal. method consists of ultrasound-assisted extraction in methanol/acetonitrile (1:1, volume/volume,) acidified with acetic acid-ammonium acetate buffer (pH 4), cleanup on a HybridSPE-Phospholipid cartridge (zirconia-coated silica cartridge), and quantification with liquid chromatog.-tandem mass spectrometry (LC-MS/MS). Acceptable accuracy (internal standard-corrected recovery: 70%-120%) and intra- and inter-day precision (coefficient of variation: <15%) were obtained for both plasma and whole-body tissue samples. In addition, low method detection limits were achieved for both plasma (0.0077 to 0.93 ng mL-1) and whole-body tissue (0.022 to 4.3 ng g – 1 wet weight), although the developed method is simple and fast – a batch of 24 samples can be prepared within 6 h, excluding the time for measurement with LC-MS/MS. The developed method was successfully applied to the anal. of PPCPs in plasma and whole-body tissue samples of fish collected in a treated wastewater-dominated stream, for a comprehensive evaluation of their bioconcentration properties. The anal. method developed in the present study is sufficiently accurate, sensitive, and rapid, and thus highly useful for the comprehensive evaluation of PPCP residues in fish and would aid in future exposome and risk assessment. This study involved multiple reactions and reactants, such as 2-(4-(1-Hydroxy-4-(4-(hydroxydiphenylmethyl)piperidin-1-yl)butyl)phenyl)-2-methylpropanoic acid (cas: 83799-24-0Recommanded Product: 83799-24-0).
2-(4-(1-Hydroxy-4-(4-(hydroxydiphenylmethyl)piperidin-1-yl)butyl)phenyl)-2-methylpropanoic acid (cas: 83799-24-0) belongs to piperidine derivatives. Piperidine has a role as a reagent, a protic solvent, a base, a catalyst, a plant metabolite, a human metabolite and a non-polar solvent. Piperidine derivatives bearing a masked aldehyde function in the ε-position are easily transformed into quinolizidine compounds through intramolecular reductive amination.Recommanded Product: 83799-24-0
