2-Iminothiolane has found utility in the growing area of antibody–drug conjugates by serving as a lysine-thiolating agent and the junction between the antibody and the cytotoxic payload during random conjugation of a monoclonal antibody. 2-14C-Iminothiolane was prepared from commercially available [14C]KCN using a four-step sequence in an overall 10% radiochemical yield. Stable-labeled 2-13C,15N-iminothiolane was also prepared from [13C15N]KCN in a similar manner. The. labeled Traut's reagent produced by this sequence showed comparable reactivity as the commercially available unlabeled reagent with a representative monoclonal antibody and could serve as highly informative analytical tools to investigate antibody–drug conjugate formation via the random conjugation process.
