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: 180.16
  • log P ≤ 5 (Crippen): -3.38
  • H-bond donors ≤ 5: 5
  • H-bond acceptors ≤ 10: 6

Passes all four rules.

¹³C NMR shifts, predicted

Predictions, not measurements; each names its method. A measured log P, where a source reports one, is under Physical properties.

Safety
