Quetiapine sulfoxide is a metabolite of quetiapine, resulting from the oxidation of the sulfur atom in the quetiapine molecule to form a sulfoxide group. Quetiapine acts as an agonist of 5-HT receptors and an antagonist of dopamine receptors. In the field of environmental chemistry, the study of metabolites like quetiapine sulfoxide is important for understanding the fate and impact of compounds in the environment. Analytical chemistry benefits from the study of quetiapine sulfoxide in developing sensitive and specific methods for detecting and quantifying compounds and their metabolites in biological and environmental samples. Advanced analytical techniques, such as liquid chromatography-mass spectrometry (LC-MS), are used to monitor the presence of these compounds in water, soil, and tissue samples.
