About Us:

Cambridge Isotope Laboratories, Inc. (CIL) is the world’s leading producer of stable isotopes and stable isotope-labeled compounds. With approximately 750 employees and laboratories in four countries, 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). CIL’s products are utilized in laboratories, medical, government and academic research centers and health care facilities worldwide.

We are proud that CIL products have contributed to medical advancements in cancer research, new-drug development, environmental analysis, and medical diagnostic research. In the past decade, as the fields of proteomics and metabolomics have developed as leading techniques for determining biomarkers for disease presence, progression and the monitoring of therapeutic response, CIL has worked closely with industry leaders and researchers to provide the stable isotope-labeled tools needed for improved quantitation and qualification of complex biological systems.

After decades of research, stable isotopes have found their place in an ever expanding commercial scale applications in pharmaceuticals, semiconductors, flat panel displays as well as other high technology fields specifically with deuterium oxide (D2O) and deuterium gases. Pharmaceutical companies have begun to investigate deuteration of molecules that may provide advantages over their existing nondeuterated counterparts. In addition, increasing research into the potential medical advantages of new deuterated drugs is also occurring. In high technology, deuterated organic molecules and deuterium gas are commonly used in the manufacturing of microelectronics and OLEDs, which contribute to the increased lifetime of the devices.
