About ViraChem
An EU-based platform coordinating peptide manufacturing and sourcing for research and preclinical development.
Mission
To supply research laboratories with peptides whose identity and purity are measured, not assumed. Every lot is released against its grade’s specification — HPLC purity and MS identity, Karl Fischer water content, LAL endotoxin on the In Vivo grade — and carries a lot number that follows the material from raw powder to vial.
What every lot carries
- One lot number — on the vial, the certificate and the invoice
- A certificate of analysis (HPLC purity, MS identity), published in the CoA vault once issued
- A safety data sheet and written storage and handling instructions
ViraChem operates as a layer coordinating sourcing, synthesis, purification, and downstream processing of high-purity peptides and fine chemicals.
Through established manufacturing partnerships in Poland, we support research and preclinical workflows with services including peptide synthesis, lyophilization, and fill & finish.

What we offer
EU service models for research and preclinical supply.
The specifications we release against
Three research grades, one per use. Each row is a test a lot must pass before it ships; the same table decides what its certificate of analysis reports. These are the live specifications, read from the same source as every product page.
