EC number: 276-911-4
CAS number: 72829-25-5
Red 024:1 is a red-brown powder. The
melting point and boiling point was identified to be greater than 330
relative density of test item at 20 °C was found to be 1.6661 g/cm³.
median particle size was 119.378 µm. The
partition co-efficient n-octanol/water of Reactive Red 024:1 was
determined to be Pow = 3.02 x 10-4, Log Pow = -3.52. The
water solubility at 20 °C was determined to (without correction for the
purity): = 434 g/l.
surface tension was determined to be 62.889mN/m
at 20 °C. The
auto-ignition temperature of test item cannot be determined, as no
auto-ignition occurred up to 550 °C. No
ignition was observed throughout the course of a flammability study,
hence test material is considered as not highly flammable. The
analysis of the chemical structure reveals no alerts for explosive
properties for Reactive Red 24:1. 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.
