Hexasodium 2,2'-[vinylenebis[(3-sulphonato-4,1-phenylene)imino[6-morpholino-1,3,5-triazine-4,2-diyl]imino]]bis(benzene-1,4-disulphonate)

Endpoint summary

Description of key information

The substance is a bright yellow powder, solid at 20 °C. The test substance when tested according to OECD test guideline 102 for melting point and OECD test guideline 103 for boiling point determination did not melt or boil until 350 °C. Average relative density at 20 °C was found to be 1.2450 g/cm³. The median particle size data is found to be 27.007 µm. The partition co-efficient n-octanol/water at 20 °C was determined to: Pow =3.72 X 10-5, Log Pow = -4.42. The water solubility at 20 °C was determined to 153.1 g/l (without correction for the purity). The surface tension was determined to be 49.809 mN/m at 20 °C. No auto-ignition up to 550 ° C could be detected. No ignition was observed throughout the course, hence, it is considered as not highly flammable. The analysis of the chemical structure reveals no alerts for explosive properties. The calculated chemical oxygen balance is above the trigger value of -200, but the determination of the exothermic decomposition energy demonstrated an energy release below the critical value of 500 J/g. Therefore, the substance is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008 and no further testing are required. In accordance with Column 2 of REACH Annex VII, this study does not need to be conducted as this substance is incapable of reacting exothermically with combustible materials on the basis of its chemical structure.
