4-(Trifluoromethoxy)aniline-15N is a nitrogen-15 isotopically labeled derivative of 4-(trifluoromethoxy)aniline, offering enhanced utility in NMR spectroscopy and mass spectrometry applications. The incorporation of the 15N isotope provides distinct advantages in tracking molecular interactions, metabolic studies, and structural elucidation due to its non-zero nuclear spin. The trifluoromethoxy group enhances the compound's stability and lipophilicity, making it suitable for pharmaceutical and agrochemical research. This labeled compound is particularly valuable in mechanistic studies, where precise isotopic tracing is required. Its high purity and well-defined isotopic enrichment ensure reliable performance in analytical and synthetic applications.
