Purity
All of our products stand out due to the high performance demonstrated in applications. The chemical purity is always higher than 95%, usually higher than 98%.
GMP
PharmaSynth follows the GMP production guidelines ensuring a validated manufacturing process that involves qualified personnel and premises that suit the operations to be carried out.
Test labeled
We provide an optimization of labeling, as our regular precursor batches are test labeled in Karolinska Institute. The specific activity is usually higher than 10 000 Ci/mmol in 11C labeling (the best achieved is desmethyl-raclopride 52000 Ci/mmol).
