Used primarily in research settings as a metabolite of the antidepressant paroxetine, this compound helps in studying drug metabolism and pharmacokinetics. It aids in understanding the biological pathways involved in the breakdown of selective serotonin reuptake inhibitors (SSRIs). Due to its structural similarity to paroxetine, it is also relevant in forensic analysis and toxicology screenings to identify drug use and monitor metabolic profiles. Not intended for therapeutic use, it serves as a reference standard in analytical chemistry for detecting and quantifying paroxetine and its metabolites in biological samples.
