Tritium Radiosynthesis

A person wearing safety glasses, a lab coat, a purple glove, and a blue sleeve cover operates equipment in a laboratory fume hood. The fume hood has gauges, knobs, and a glass door. The surrounding lab appears clean and sanitized as they conduct genetic toxicology experiments.

Tritium Radiosynthesis Services

Pharmaron’s team of tritium experts work together with you to develop a radiolabelling strategy for the compound(s) and desired applications including late-stage lead optimization of candidate compounds. Our team provides advice on custom tritium-labelled compounds and optimal position(s) of the tritium [3H] label(s).
