Additional information

Justifications for a read-across from data of monosodium succinate to succinic acid:

The read-across from the succinate to succinic acid seems justified, as both are well water soluble and will be in the ionised form in dilute aqueous solutions, to give the same anion. The different molecular weights were considered.

Justification for classification or non-classification

No classification is derived from the NOAELs.
