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
