Tested and Verified
Before It Ships.
No lot reaches the catalog until an independent laboratory has tested it. HPLC-DAD confirms both purity and identity, and every lot carries its own ID tied straight to the certificate of analysis behind it.

Per-lot
Checked three ways before it ships.
Three steps stand between a batch arriving here and it appearing on this site. Each one is documented, and each one is visible to you.
Independently tested
The assay is run by an outside laboratory, not by us. Reverse-phase HPLC-DAD establishes the purity figure and confirms identity against a reference standard.

Documented purity
The measured figure is tied to the lot and printed on its certificate before the compound is listed. No number appears on this site without a result behind it.
