Your trusted partner for peptide synthesis
While our catalog spans 32,000+ research chemicals, our expertise is products involved in peptide synthesis workflows.
Top peptide chemists around the world trust our amino acids to simplify complex syntheses, conquer tough sequences, and save valuable time and resources.
The collection
Our team has spent decades curating a catalog of high-purity reagents—amino acids, linkers, and custom building blocks—that power both cutting-edge discovery and everyday research.
Chem-Impex offers a large library of peptides spanning:
- Amino Acids: Natural and unnatural, Fmoc- or Boc-protected
- Protecting Groups: Fmoc (base-labile), Boc (acid-labile)
- Resins: Wang, Rink Amide, PEG or polystyrene
- Coupling Reagents: DIC, HBTU, HATU, PyBOP
- Solvents: Traditionally DMF/NMP; greener options include DMSO blends, isopropanol, ethanol
Why peptides
Peptides are small chains of amino acids that play a big role in modern science. They combine the best of both worlds: the simplicity of small molecules and the precision of biologics like antibodies. You’ll find peptides at the heart of breakthrough drugs for cancer, diabetes, and infectious diseases—as well as in vaccines, diagnostics, and materials science.
Right now the peptide industry is undergoing a significant transformation, driven by a demand for more efficient, scalable, and sustainable manufacturing processes.
