BOC Sciences is committed to providing customers with high-quality and stable isotope carbon-13 labeled peptides, amino acids, nucleic acids, steroids, APIs, impurities, inhibitors, metabolites, carbohydrates, polymers, fatty acids and lipids, as well as other products.


There are three common isotopes of carbon, which are carbon-12 (12C), carbon-13 (13C) and carbon-14 (14C). Carbon-12 is the most common form of carbon isotope and makes up almost 99% of the carbon element on the earth. The second most common carbon isotope is carbon-13, which accounts for about 1% of the carbon in the natural world. Both carbon-12 and carbon-13 are called stable isotopes of carbon, and their atomic energy can exist stably for a long time without being affected by the half-life. Carbon-14 is radioactive, extremely rare and unstable, and will not decay over time. As a stable isotope of carbon, carbon 13 has the characteristics of non-toxic, non-radioactive, stable performance, high sensitivity, and strong specificity. It revealed advantages as a tracer and has been widely used in research fields such as biomedicine.

Carbon-13 labeled compounds

Carbon-13-labeled compounds refer to non-radioactive-labeled compounds that use stable isotope carbon-13 instead of the original carbon. Carbon-13 labeled compounds retain the same chemical and biological properties as their unlabeled counterparts, which is significant for chemistry and biology research. Carbon-13 can be detected by sensitive mass spectrometry technology to distinguish carbon-13 from natural carbon. Moreover, non-radioactive carbon-13 labeled compounds, including amino acids, peptides, carbohydrates, nucleic acids, lipids, steroids, vitamins, and other drugs, could be used as sensitive tracers to study organic chemical reactions and biochemical reactions more conveniently. Therefore, carbon-13 has a wide range of applications.
