Carbon-14 Radiosynthesis

A scientist wearing a white lab coat and blue gloves works in a laboratory, manipulating equipment inside a fume hood. Various controls, gauges, and equipment are visible around the fume hood, indicating a high-tech environment for preclinical ADME studies.

Carbon-14 Radiosynthesis Services

Pharmaron’s radiosynthesis team prepares and releases radiolabelled test compounds for use in non-clinical studies, clinical drug development and environmental fate studies. We provide expert advice on radiosynthetic chemistry, synthesis routes and where to place the radiolabel in the molecule so that it is located in a metabolically stable position. This includes molecules subject to cleavage that may require a radiolabel in two positions to adequately characterize their metabolites and metabolism.

Pharmaron provides consultation on synthesis routes, label position, specific activity and product specification and has dedicated project teams with chemists and analysts.

The team is experienced with volatile compounds, aromatics, heterocyclics, chiral compounds, peptides (peptide synthesis via solution chemistry/synthesizer), proteins (including radiolabelling by fermentation), fusion proteins, oligos, conjugates, polymers and constructs.
