What we can prove,
and nothing more.

BetterChem publishes analytical facts about the material in the vial: what it is, how pure it is, who measured it, and when. We do not publish claims about what any material does, because that is not something a certificate can establish.

Identity confirmation

Each lot is analysed by electrospray ionisation mass spectrometry and the observed mass is compared against the expected molecular weight for the sequence. A lot that does not match is rejected before it reaches inventory.

Purity determination

Purity is determined by reverse phase HPLC with UV detection. We publish the figure the independent laboratory reports, not a rounded figure and not a specification target.

Independent analysis

Testing is performed by a third party analytical laboratory that has no commercial interest in the result. We do not self certify.

Lot traceability

Every vial carries a lot number that resolves to the certificate for that specific batch. A certificate describes the lot named on it and no other.

Reading a certificate

A certificate of analysis is only as useful as its specificity. Ours state the lot, the laboratory, the analytical method, the date of analysis, and the result. If any of those are missing from a certificate you are shown, by us or by anyone else, it is not telling you what it appears to.

Handling and storage

Storage conditions, appearance, and solubility are recorded on each product specification so that conditions are reproducible between laboratories. Materials are supplied lyophilised unless stated otherwise and should be transferred to their specified storage conditions promptly on receipt.

Beyond storage and solubility, BetterChem does not publish handling or preparation guidance. Determining a suitable laboratory protocol is the responsibility of the qualified researcher.
