About XYN98
A peptide manufacturer that kept the whole process in-house — synthesis, purification, lyophilization, testing and dispatch — since 2017.
Built by chemists who got tired of unverifiable supply
XYN98 began as a small synthesis bench serving a handful of university labs. The problem we kept running into was not demand — it was traceability. Compounds arrived with certificates that described a different batch, or with no analytical data at all.
So we built the opposite kind of operation. Every step stays inside our own facility, every lot gets tested before release, and every vial carries a batch code that maps to a document you can actually read. Nine years later that is still the whole idea.
- ✓ Solid-phase synthesis, purification and lyophilization in-house.
- ✓ HPLC and LC-MS testing on every released lot.
- ✓ Batch-level documentation shipped with each order.
- ✓ Custom synthesis, fill volumes and private labeling.

Orders delivered
From raw material to released vial
Four controlled stages, each with its own record. Nothing moves to the next step until the previous one is signed off.
Synthesis
Solid-phase assembly with reagent and resin records kept per batch.
Purification
Preparative HPLC separates the target peptide from truncated sequences.
Lyophilization
Controlled freeze-drying into a stable powder, then vial filling and crimping.
Release testing
Purity and identity confirmed before the batch is cleared for sale.

What "99%+ purity" actually means here
Purity is measured by reverse-phase HPLC as the area percentage of the principal peak. We publish the chromatogram rather than just a number, because a percentage without the trace behind it tells you very little.
Identity is then confirmed independently by LC-MS against the theoretical molecular mass. Both records are attached to the batch and travel with your order.
What we hold to
Evidence over claims
If we state a number, we publish the method and the trace behind it.
Own the process
We do not broker other people's stock and call it ours.
Research-first
Products are sold strictly for laboratory research, and we say so plainly.
