Purity & assay report
HPLC purity at 99.741% with 20.92 mg quantitative assay.
Heavy metals report
ICP-MS panel for arsenic, cadmium, lead and mercury. All four below detection limits.
TFA report
Trifluoroacetic acid is a residual solvent from peptide synthesis. HPLC purity does not see it. This batch tests separately and returns "not detected."
