With increasing requirements from institutional review boards (IRBs) and governmental agencies, partnering with Cambridge Isotope Laboratories, Inc. (CIL) for your next stable isotope cGMP project can help ensure your regulatory compliance. With the world’s largest 13C and 18O isotope-separation plants, CIL is able to provide the raw materials necessary for your project. Your compound of interest most likely already appears in CIL’s extensive list of research compounds – if not, CIL’s team of PhD chemists can determine the best method of synthesis for incorporating 13C, 15N, deuterium, 17O, and/or 18O into your compound. CIL has manufactured bulk active pharmaceutical ingredients (APIs) since 1994. It recently added a 15,000-square-foot, state-of-the-art cGMP facility to complement its existing cGMP facilities.
