Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Due to high molecular weights of main constituents, i.e. above 500 g/mol, a high water solubility of 325 g/l at 20 °C and a low log Pow of -1.21 at 20 °C, the absorption rate is expecetd to be low. In experimental studies by oral route, a certain amount of test substance proved to be absorbed and systemically distributed.

In studies by dermal route, local skin discolouration was noted, indicating a certain absorption.

Based on the molecular structrure, metabolism is expected to imply reactions at the diazo bond and functionalisation of molecules to increase solubility and excretion.
