Documentation for
rigorous research practice

Researchers who understand their materials, documentation, and compliance context produce better science. These guides are written by Arcovex for our buyer community — not marketing copy repurposed as education.

Frequently Asked Questions
What qualifies as a legitimate research use for these compounds?
+

Legitimate uses include in vitro cell culture experiments, molecular biology assays, analytical method development and validation, HPLC reference standard preparation, and formally approved animal model studies with appropriate IACUC oversight. The defining criterion is that the work occurs in a controlled laboratory setting, under qualified supervision, for the purpose of generating research data.

Personal use, clinical administration, and consumer product development are not legitimate uses, regardless of the buyer's credentials or intentions.

How do I verify that a COA actually corresponds to the lot I received?
+

Every vial label includes a lot number and a QR code. The lot number on your COA must match the lot number on your vial label. If it does not, contact us before using the compound. See Arcovex Verified for details on the planned verification record structure.

Do your compounds require any special import permits?
+

Import requirements vary by compound, jurisdiction, and end-use context. Some peptides and research chemicals are subject to scheduling, import notification requirements, or country-specific regulatory controls. Arcovex provides SDS documentation and compound classification information, but the buyer is solely responsible for determining import legality and obtaining any required permits in their jurisdiction.

We recommend consulting your institution's regulatory affairs or compliance office before placing an international order.

What does "purity" mean on an Arcovex COA, and what method is used?
+

Purity on Arcovex COAs is reported as percent area by HPLC — specifically, the area percentage of the target compound peak relative to all detected peaks in the chromatogram. This is the standard analytical method for peptide purity quantification. It is not a mass-based purity measurement and does not account for water content or counter-ion mass unless specified.

All HPLC testing is performed by our third-party analytical laboratory using calibrated instrumentation with documented methods. Raw chromatogram data may be available upon request as part of the analytical report.

Can I request a compound not currently listed in your catalog?
+

Yes. We source and verify compounds beyond our published catalog on a case-by-case basis for qualified institutional buyers. Custom sourcing requests require a research inquiry with compound specification, target quantity, and a description of the research application.
