Research peptides you can actually trace.
High-purity peptides for laboratory research, each lot third-party assayed and shipped with a certificate of analysis you can track from synthesis to release. No claims. No guesswork. Just data.
Every lot has a record. Pull it up.
Enter the lot or batch number printed on your vial to retrieve its certificate of analysis, analytical panel, and release status.
Each COA is tied to a single lot. Records are immutable once a lot is released.
A few from the catalog.
A selection of our lot-traced reference materials. Open the full catalog to browse and filter every peptide.
All products are sold strictly as research chemicals / reference materials for in-vitro laboratory research and analytical use. They are not drugs, supplements, cosmetics, or food, and are not for human or animal consumption. No therapeutic or diagnostic claims are made or implied.
Four assays before a lot is released.
An independent ISO/IEC 17025 lab runs the panel. If a lot misses spec, it is quarantined and never reaches inventory.
Purity
Reverse-phase HPLC quantifies peptide purity against impurity peaks. Release spec ≥98%.
Identity & mass
Mass spectrometry confirms molecular weight matches the target sequence within tolerance.
Water content
Karl Fischer titration measures residual moisture in the lyophilized material.
Documentation
A COA, GHS-format SDS, and handling sheet are issued and bound to the lot record.
Research buyers only. We hold the line.
Vectra Research sells exclusively to qualified researchers, institutions, and laboratories. Every order requires acknowledgement that materials are for in-vitro research use only.
Straight answers, no claims.
What does "research use only" mean here?+
Our products are reference materials intended solely for in-vitro laboratory research and analytical method development. They are not drugs or supplements, carry no therapeutic claims, and are not for human or animal use.
How do I track a lot's COA?+
Enter the lot number printed on the vial into the COA tracker above. You'll see the analytical panel and the chain of custody from synthesis through QC to release, plus a verification reference bound to that lot.
What analytical data comes with each lot?+
HPLC purity, LC–MS identity and observed mass, molecular formula, Karl Fischer water content, and residual content — all on a COA issued by an independent ISO/IEC 17025 laboratory, alongside a GHS-format SDS.
How should materials be stored and handled?+
Lyophilized peptides ship at ambient temperature and should be stored desiccated and frozen on receipt. Refer to the lot's SDS and handling sheet for specifics. Handle only in an appropriately equipped laboratory.
