Each peak is a nominal mass with its abundance-weighted exact mass, as a percentage of the tallest, from IUPAC natural isotope abundances.

Computed from the structure with RDKit 2026.09 when this page was built, beside PubChem's own computed values from its record; where the two differ, both are shown.

Drug-likeness: Lipinski’s rule of five

  • Molecular weight ≤ 500: 323.2
  • log P ≤ 5 (Crippen): -2.45
  • H-bond donors ≤ 5: 5
  • H-bond acceptors ≤ 10: 8

Passes all four rules.
