Precision Research.
Research compounds supplied from the United States to qualified purchasers. Three things a batch has to answer for before it is released.
- Identity
- Is it what the label says? Mass spectrometry identifies a molecule by its molecular weight, and confirms the vial holds the named compound.
- Purity
- How much of it is in the vial? HPLC separates everything in the vial and measures how much is the compound and how much is anything else.
- Traceability
- Which batch is yours? The certificate is for the exact lot in your box, available on request, never a representative one.

Three ways to find what you need.
Research Standards
Built for Precision
Release requires independent analytical testing, and the certificate for that batch is available on request.
Identity. Purity. Traceability. Consistency. Nothing less.
Identity Confirmed
Mass spectrometry weighs the molecule and compares it against the theoretical mass of the stated sequence.
Purity Measured
Reversed-phase HPLC, reported as a percentage of total peak area. The figure is the batch's, and it is published on the batch's certificate.
Independent Testing
Release requires analysis by a third-party laboratory with no commercial interest in the result.
Batch Certificate
A certificate specific to the lot in your box, with the lot number on both, available on request.
Research Use Only
Supplied for Research.
NORTEAVA supplies compounds to qualified purchasers for laboratory use only.
Nothing we sell is for human or veterinary use.
A certificate of analysis for the lot in your box is available on request with every order.
Orders are fulfilled from the United States.

Notes on quality systems, analysis and longevity science.
Each note links to the primary public literature. We cite rather than summarize, and we make no claim of clinical benefit for materials supplied for research use only.
