Description of key information

Adsorption/desorption:

Based on Annex VIII, Column 2 the study does not need to be conducted because the substance tetrasodium (3E)-5-amino-3-{2-[4-(4-{2-[(2E)-8-amino-1-oxo-3,6-disulfonato-1,2-dihydronaphthalen-2-ylidene]hydrazin-1-yl}-3- hydroxyphenyl)-2-hydroxyphenyl]hydrazin-1-ylidene}-4-oxo-3,4-dihydronaphthalene-2,7-disulfonate dicopper (CAS no. 28407-37-6) has low octanol water partition coefficient. The log Kow of target chemical tetrasodium (3E)-5-amino-3-{2-[4-(4-{2-[(2E)-8-amino-1-oxo-3,6-disulfonato-1,2-dihydronaphthalen-2-ylidene]hydrazin-1-yl}-3- hydroxyphenyl)-2-hydroxyphenyl]hydrazin-1-ylidene}-4-oxo-3,4-dihydronaphthalene-2,7-disulfonate dicopper (CAS no. 28407-37-6) is -0.77 dimensionless and adsorption potential of this substance is related to this parameter.
