Description of key information

Reactive Red 245 is a dark red-brown powderThe melting point was determined to be higher than 300 °C, therefore the data requirements for boiling point as well as vapour pressure were waived. The density at 22 °C is 1750 kg/m³ with a median of mass distribution of 56 µm and a calculated partition coefficient between n-octanol and aqueous phase of ca -10.6 (log Pow). The water solubility of the test substance is 339 g/L at 20 °C and the fat solubility is lower than 0.05 mg/100g at 37 °C. The surface tension of aqueous solution at 20 °C lies between 66.3 - 66.4 mN/m at a concentration of 1 g/L and between 55.1 – 55.4 mN/m at a concentration of 10 g/L. The auto-flammability temperature of the test substance is 350 °C and the test substance is not highly flammable. The test substance is also not explosive, has no oxidizing properties and is thermally stable, but dissociates in water.
