Additional information
Acid Red 249:1 is an odourless and very soluble dark red powder. The substance decomposes before melting and boiling, for this reason neither vapour pressure nor flash point are defined. Surface tension is not a desirable property of the substance.
Acid Red 249:1 has a relative density of ca. 1.5 and a log Kow of ca. -1.6. The median mass diameter after 2 minutes of ultrasonic treatment is in the range of the thoracic fraction (10 – 100 µm).
The compound is presumably non flammable, non oxidising, non explosive and has no spontaneous ignition property.
The physical and chemical properties of the multicomponent Acid Red 249:1 have been evaluated based on the tests conducted on one of the two components, the substance is composed by the sodium salt and the acidic form of the same substance.
