Stable Isotopes

Our stable isotope-labelled standards, including deuterated, 13C, and 15N-labelled compounds, are fundamental tools in bioanalytical methods. These isotopes offer unparalleled precision for the quantification and tracking of APIs, metabolites, and impurities. Widely used as internal standards in pharmacokinetic studies, they enhance the accuracy and sensitivity of analytical protocols, making them indispensable in drug development, metabolic research, and environmental studies. Trusted by researchers and bioanalytical laboratories worldwide, our stable isotope standards are recognized for their purity and consistency.
