Stable Isotope Compounds

We provide over 200 stable isotope labeled compounds for use as mass spectroscopy internal standards and for obtaining clearer results when analyzing NMR samples, including many hard to find stable isotope labeled compounds useful for both research and analytical communities. Many of these compounds can also be provided in larger quantities than those listed in the catalog. Please inquire for pricing and availability. We can also provide custom synthesized, labeled versions of nearly any compound that you may need as well as custom versions of our catalog compounds with different substitution patterns or additional labeled atoms. Where applicable labeled and unlabeled CAS numbers are provided. All stable isotopes require overnight shipping methods.
