Isotope pattern
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.
Predicted
- log P
- -2.21 Crippen (Wildman and Crippen 1999)
- log S (water solubility)
- -1.07 ESOL (Delaney 2004), log mol/L
- Synthetic accessibility
- 4.43 SA score, 1 easy to 10 hard (Ertl and Schuffenhauer 2009)
Drug-likeness: Lipinski’s rule of five
- Molecular weight ≤ 500: 483.16
- log P ≤ 5 (Crippen): -2.21
- H-bond donors ≤ 5: 7
- H-bond acceptors ≤ 10: 12
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
No GHS hazard classification was found in the sources.
