THJ2201 N-pentanoic acid metabolite (CRM) (THJ 018 N-pentanoic acid metabolite) is primarily used as a reference standard in analytical laboratories for research and forensic purposes. It plays a critical role in the identification and quantification of synthetic cannabinoids and their metabolites in biological samples. This compound is essential for developing and validating analytical methods, such as liquid chromatography-mass spectrometry (LC-MS), to ensure accurate detection of drug use. It is particularly valuable in forensic toxicology for investigating cases involving synthetic cannabinoid consumption, aiding in legal and medical assessments. Additionally, it supports studies on the metabolism and pharmacokinetics of synthetic cannabinoids, contributing to a better understanding of their effects and potential health risks.
