Analytical Results
| Test | Result |
|---|---|
| Identity (LC-MS) | Semaglutide |
| Purity (RP-HPLC-UV, area %) | 99.66% |
| Net Content | 14.84 mg |
Method: purity by reversed-phase HPLC with UV detection, reported as peak area percent; identity by liquid chromatography–mass spectrometry (LC-MS) on the same sample. Full chromatographic conditions are held on file and issued on request against this search code.
Chromatogram
Mass Confirmation
| Charge state | m/z (observed) |
|---|---|
| [M+4H]4⁺ | 1029.417 |
| [M+3H]3⁺ | 1372.221 |
| [M+2H]2⁺ | 2057.827 |
Charge states are assigned by matching each observed m/z against the declared molecular weight; every peak in this acquisition matches within 0.06 u.
