Abstract: This manuscript presents the development, validation and application of a multi-residue supercritical fluid chromatog. coupled with tandem mass spectrometry method for the anal. of 140 chiral and non-chiral chems. of emerging concern in environmental samples, with 81 compounds being fully quant., 14 semi-quant. and 45 qual., validated according to European Medicine Agency (EMA) guidelines (European Medicines Agency 2019). One unified LC-MS method was used to analyze all analytes, which were split into three injection methods to ensure sufficient peak resolution The unified method provided an average of 113% accuracy and 4.5% precision across the analyte range. Limits of detection were in the range of 35 pg L-1-0.7 μg L-1, in both river water and wastewater, with an average LOD of 33 ng L-1. The method was combined with solid-phase extraction and applied in environmental samples, showing very good accuracy and precision, as well as excellent chromatog. resolution of a range of chiral enantiomers including beta-blockers, benzodiazepines and antidepressants. The method resulted in quantification of 75% of analytes in at least two matrixes, and 56% in the trio of environmental matrixes of river water, effluent wastewater and influent wastewater, enabling its use in monitoring compounds of environmental concern, from their sources of origin through to their discharge into the environment. In the experiment, the researchers used many compounds, for example, 2-(3-(Hydroxy(phenyl)methyl)phenyl)propanoic acid (cas: 59960-32-6Formula: C16H16O3).
2-(3-(Hydroxy(phenyl)methyl)phenyl)propanoic acid (cas: 59960-32-6) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Formula: C16H16O3
