Stable Isotope Labelled compounds

CIL specializes in the process of labeling biochemical and organic compounds with highly enriched, stable (nonradioactive) isotopes of carbon, hydrogen, nitrogen and oxygen. Our chemists substitute common atoms (e.g., 1H, 12C, 14N, 16O) with rare, highly valued isotopes (e.g., 2H or D, 13C, 15N, 18O) so that the final product can be readily measured or traced using mass spectrometry (MS) or nuclear magnetic resonance (NMR).
