Stable Isotope Compounds
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.
