Description of key information

The substance is a light blue powder, placed on the market as solution, i.e. in a non solid or granular form.

Physicochemical properties of the substance were evaluated by means of a read across approach. In particular, Similar Substance 01, i.e. an isomer of target substance, and Similar Substance 02, i.e. a structural analogue of the target substance, were considered. Based on the structutral similarities, no significant differences on the physicochemical properties are expected.

Melting point is expected to be well above 300 °C; moreover, the substance is expected to have a relative density between 1 and 2, a negative partition coefficient (log Pow ca. -3) and a high water solubility, i.e. > 10 g/l at 20 °C.

Direct Blue 273 is expected to be non autoflammable, non flammable, non oxidising and non explosive.
