Cagrilintide mass & m/z.
Molecular formula C194H312N54O59S2 · Secretagogue & Regulatory. Mass and m/z below are computed from the verified molecular formula; the isoelectric point is computed only where the sequence permits.
Molecular mass
| Average molecular weight | 4409.07 g/mol |
|---|---|
| Monoisotopic mass | 4406.2515 Da |
Cross-check: matches the verified record (monoisotopic 4406.2515 Da, average 4409.08 g/mol). Average mass varies ~0.01–0.1 Da between atomic-weight tables.
ESI-MS m/z (positive mode)
| Charge state | m/z (monoisotopic) | m/z (average) |
|---|---|---|
| [M+1H]1+ | 4407.2588 | 4410.08 |
| [M+2H]2+ | 2204.1330 | 2205.54 |
| [M+3H]3+ | 1469.7578 | 1470.70 |
| [M+4H]4+ | 1102.5702 | 1103.27 |
| [M+5H]5+ | 882.2576 | 882.82 |
Isoelectric point (pI)
Not computed
pI is not published for this compound — modified N-terminus (acyl). A residue-pKa pI calculation is only valid for a linear, unmodified peptide of the standard 20 L-amino acids with free termini; computing one here would be a fabricated value.
Method & provenance
- Mass: element arithmetic over the verified molecular formula. Monoisotopic uses most-abundant-isotope masses (CODATA/AME); average uses IUPAC 2021 standard atomic weights.
- ESI-MS m/z: positive-mode protonated ions [M+nH]n+, m/z = (M + n·1.007276) / n, from the computed monoisotopic (and average) mass.
- pI: computed only for linear, unmodified peptides of the standard 20 L-amino acids with free termini; otherwise flagged. Values are analytical/characterization data only — no efficacy, dosing, or human-use meaning.
