Additional information

The published experimental data on water solubility ofpenta-1,3-diene report poor solubility of this chemical. These data arewell within the range of 325 -1544 mg/L calculated with the US EPA developed QSAR models for water solubility estimation.


Based on the water solubility data summarized above, the value of 690 mg/L is adopted for the purpose of this CSA. Therefore,penta-1,3-dieneis slightly soluble in water.
