about us

Where Research Integrity Became Our Mission

Puratek was founded by researchers who kept receiving compounds with no traceable documentation. Our answer: test every batch independently, publish the result, print the lot number on the vial.

Puratek Begins

Built around independent testing, clear transparency, and consistent batch standards.

Public COA library

Certificates moved out of email and onto the product page, making verification faster, simpler, more transparent, and instantly accessible for researchers.

OUR PURPOSE

A higher standard for
research transparency.

Our purpose is simple: make verification, documentation, and traceability part of every batch—not something researchers have to ask for.
01
Our vision

Make verification the default, not the upgrade

Researchers should never have to request proof of what they bought. We publish the assay first and let the documentation do the selling.
02
Our vision

A supply chain a scientist can audit end to end

From synthesis lot to shipping label, every step traceable from a single batch number — the standard we hold ourselves to as the catalog grows.

Core values

01

Evidence Over Claims

If we cannot show the assay behind a number, we do not print the number.

02

Radical Documentation

Certificates are public by default and tied to the exact lot in your package.

03

Scientific Rigour

HPLC and mass spectrometry on every lot, run by a lab with no stake in the result.

04

Full Traceability

One batch number connects the synthesis lot, the assay and the shipment.

05

Consistency

The same specification lot after lot, so your results stay comparable over time.

06

OUR PURPOSE

How a batch becomes releasable

Every batch must pass Puratek’s 8x testing standard before it is approved for release. These four checkpoints summarize the key stages of that process. If a batch fails any required test or verification step, it does not ship.

01

Synthesis & Intake

Each incoming lot is logged, documented, and assigned a Puratek batch number for traceability.
02

Purity & Identity Testing

Independent laboratory testing verifies purity and confirms the compound identity against the expected specification.
03

Quality & Batch Verification

Testing results, lot details, and supporting documentation are reviewed to confirm the batch meets Puratek’s required quality standards.
04

Final Approval & COA

After all eight testing requirements are successfully completed, the batch is approved for release and its batch-specific COA is published.

What Researchers Say

Questions Before You Order Confidently

Are Puratek products for human use?
 No. Every product we sell is strictly for laboratory and research use only. They are not intended for human or animal consumption, or for diagnostic, therapeutic or clinical use.

The certificate of analysis is published on the relevant product page and linked to the exact batch or lot number. This allows you to review the available testing documentation before placing an order.

Purity and identity testing are performed by an independent third-party laboratory with no financial stake in the result. Released batches are evaluated using methods such as HPLC and mass spectrometry.

We currently ship to the United States and Puerto Rico. Select your country or region at checkout to view the available address and delivery options.

A batch that does not meet Puratek’s required specifications is not released for sale. It is rejected rather than discounted, relabelled, or supplied without verified documentation.
