NAD+ mass & m/z.
Molecular formula C21H27N7O14P2 · 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 | 663.43 g/mol |
|---|---|
| Monoisotopic mass | 663.1091 Da |
Cross-check: matches the verified record (monoisotopic 663.1091 Da, average 663.43 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+ | 664.1164 | 664.44 |
| [M+2H]2+ | 332.5618 | 332.72 |
| [M+3H]3+ | 222.0437 | 222.15 |
| [M+4H]4+ | 166.7846 | 166.86 |
Isoelectric point (pI)
Not computed
pI is not published for this compound — no peptide sequence (small molecule). 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.
