Cambridge Isotope Laboratories, Inc. specializes in separating and producing stable isotopes and isotope-labeled compounds for chemical and biological research. By substituting common atoms with enriched, non-radioactive isotopes of carbon, hydrogen, nitrogen, and oxygen, it yields materials that can be measured or traced with mass spectrometry or NMR. These products are used by laboratories, medical and government facilities, and academic institutions worldwide to support research, diagnostics, and drug development. Headquartered in Tewksbury, Massachusetts, the company was founded in 1981 by Dr. Joel Bradley and operates within a six-company group with laboratories in five countries. It maintains ISO 13485 quality systems and cGMP production capabilities, and its catalog exceeds 15,000 products. In 2026, CIL announced a joint venture to establish advanced isotope manufacturing capabilities in Telangana, India, demonstrating its ongoing international expansion.
