Phenacetin is a compound with a history of use in various applications, it is studied for its biochemical properties and its environmental persistence. In analytical chemistry, it is frequently used as an internal standard for the quantification of other substances in complex mixtures via techniques like gas chromatography-mass spectrometry (GC-MS). In the field of environmental science, the pathways of Phenacetin degradation and its presence as a pollutant in water systems to better understand the environmental impact of such organic molecules. In the field of organic synthesis, Phenacetin role as a precursor in the preparation of other compounds through processes such as O-dealkylation. Studies on the metabolism of Phenacetin by various enzyme systems are conducted to gain insights into xenobiotic transformation and detoxification pathways in organisms.
