Physical properties
- Appearance
- Generally purplish colored. Soluble in water. Noncombustible, but accelerate the burning of combustible material. If the combustible material is finely divided, the mixture may be explosive. May spontaneously ignite in contact with liquid combustible materials. Contact with sulfuric acid may cause fire or explosion.[1]
Each value as its source reports it, with the source's number after it (listed under References). Where several sources report a property, the row shows the value most of them agree on, the rule the app uses; open the values to see every one.

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
- -1.55 Crippen (Wildman and Crippen 1999)
- log S (water solubility)
- 0.4 ESOL (Delaney 2004), log mol/L
- Synthetic accessibility
- 5.61 SA score, 1 easy to 10 hard (Ertl and Schuffenhauer 2009)
Drug-likeness: Lipinski’s rule of five
- Molecular weight ≤ 500: 118.93
- log P ≤ 5 (Crippen): -1.55
- H-bond donors ≤ 5: 0
- H-bond acceptors ≤ 10: 4
Passes all four rules.
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.
First aid
- Excerpt from ERG Guide 140 [Oxidizers]: Refer to the "General First Aid" section. Specific First Aid: Contaminated clothing may be a fire risk when dry. (ERG, 2024)[1]
