What the label has to do
A research-use-only label should identify the compound, lot, fill, storage guidance, and certificate path without making claims outside the research context. The vial and outer package should match the same release record.
Where the COA fits
The COA carries the analytical evidence: HPLC purity, LC-MS identity confirmation, and any additional release tests attached to that lot. The label should point to the COA; it should not try to replace it.
Our label
Our vial carries a short RUO statement; our outer packaging carries the longer research-use statement plus EU-relevant compliance marks; our COA carries the LC-MS and HPLC chromatograms. None of these are mixed, and accounts are reviewed before ordering access is issued.
