At Sinopeg, we’re dedicated to empowering radiopharmaceutical innovators with a comprehensive library of precursor building blocks covering all three core modules of radiopharmaceutical molecules:
Ligand (small molecules, peptides, antibodies)– for precise targeting
Linker (PEG, heterocycles, short peptides)– connecting ligand & chelator
Chelator (DOTA, DOTAGA, NOTA, PSC, etc.)– for stable radionuclide chelation
GMP-grade building blocks – independently controlled
Modular synthesis platform – individual or custom combinations available
Tailored solutions – to significantly accelerate your early-stage R&D
Our experienced synthesis team ensures high purity and stability, e.g.:
Monodisperse PEG homolog impurities ≤0.2%, single impurity ≤1%
What truly sets us apart
We’ve achieved stable, large-scale supply of critical precursors, backed by a robust quality research system and impurity identification/control capabilities. We provide complete cold kit services for IND filing, supporting dual filing in China and the U.S. and other global regulatory submissions.
End-to-end radiopharmaceutical precursor enablement
From molecular design, CMC, clinical supply to commercial production – we cover the full lifecycle, leveraging precursors to boost the efficiency of hot drug development.
What makes radiopharmaceutical R&D faster?
A deep respect for both time and quality.
As one of the few CDMOs in China solely focused on radiopharmaceutical precursors, our expertise is concentrated and our services are specialized. We look forward to partnering with you!
