Radiolabeled Chemical Synthesis

BOC Sciences provides a full range of custom radiolabeled chemical synthesis services. We have an experienced radiochemistry team that can deliver results to our customers in a timely and cost-effective manner. Our research scientists communicate directly with customers for the design and preparation of radiochemicals that meet the exact reference standards. Our team of synthetic radiochemistry experts is experienced preparing labeled compounds for non-clinical and clinical drug development.

Radioactive labeling compounds are widely used, for example, in the study of ADME in vivo. The radioactive tag can identify any metabolites and detect structurally unidentified metabolites. The use of radiolabeled chemical synthesis at an early stage allows drug developers to make informed decisions.
