Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Estimated hydrolysis half-lives for methyl 5-nitrohydrogen.isophthalate of 10.325 and 1.032 days are reported at pH 7 and 8 respectively.

Key value for chemical safety assessment

Half-life for hydrolysis:
10.325 d
at the temperature of:
20 °C

Additional information

Since methyl 5-nitrohydrogen.isophthalate has been shown to be readily biodegradable (Point 5.2.1), a study of its hydrolysis is not required. Under environmental conditions, hydrolysis is unlikely to make a significant contribution to the dissipation of methyl 5-nitrohydrogen.isophthalate compared to the rate of its removal by biodegradation.
