Quality Assurance

Tested to a standard you can cite

Batches are analysed by an independent laboratory, and the certificate for each tested lot is published in full with its verification key.

Independent verification

HPLC and mass-spectrometry analysis confirms identity and purity on every lot — never self-reported.

Certificate of Analysis

A batch-specific COA is available on request for each order, with lot number, purity, and test methodology documented.

Cold-chain handling

Lyophilised and shipped to preserve stability, with storage guidance supplied for every compound.

Testing Standards

Our testing standards

Batches are tested by an independent laboratory and the certificates are published in full. For laboratory research use only — not for human consumption.

Purity	Determined per batch by HPLC and published as measured — not stated as a minimum
Analytical method	HPLC for purity, mass spectrometry for identity
Testing laboratory	Janoshik Analytical, independent of Pioneer
Certificates	Published in full at the COA library, each with the laboratory’s verification key
Intended use	Laboratory research use only (RUO)

HPLC separates a sample into its individual components so the target compound can be measured against any impurities. The figure reported is area percent — the main peak’s share of the UV-absorbing material the detector saw, not a mass fraction of the vial. That is why the quantity result is reported separately. What a purity figure actually means.
