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: 568.92
  • log P ≤ 5 (Crippen): 10.4
  • H-bond donors ≤ 5: 1
  • H-bond acceptors ≤ 10: 5

Breaks 2 of the 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

This chemical does not meet GHS hazard criteria for 100% (2 of 2) of all reports.[1]

Safety data sheets on the supplier’s page: Biosynth, Vitas-M Laboratory, SynHet - Synthetic Heterocycles.

Always read the supplier’s safety data sheet before working with it.
