03 · Physical and chemical properties
Isoxaben properties
Every value is shown with the conditions it was measured under and the source it came from. Where sources disagree, all values are listed rather than one being picked — the difference is usually a different form of the substance, not an error.
| Property | Value | Conditions | Source |
|---|---|---|---|
| Melting point | 177.5 °C (351.5 °F) | range, midpoint shown | HSDB |
| Solubility | Slight solubility in organic solvents (methanol, ethyl acetate, dichloromethane, acetonitrile) | HSDB | |
| In water, 1.42 mg/L at pH 7 and 20 °C | HSDB | ||
| At 25 °C, methanol and ethyl acetate 50-100 mg/mL; acetonitrile 30-35 mg/mL; toluene 4-5mg/mL; hexane 0.07-0.08 mg/mL; and water 0.001-0.002 mg/mL | at 25 °C | HSDB | |
