Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is a solid which decomposes before boiling

Description of key information

Boiling point: HEBMP-H will undergo thermal decomposition without boiling.

Key value for chemical safety assessment

Additional information

The requirement to conduct a boiling point study for HEBMP-H was waived because the substance is expected to undergo thermal decomposition without boiling. This statement is supported by the evidence from the read-across DSC study which demonstrated that the sodium salt, HEBMP-xNa melts with decomposition without boiling from 129°C at 1013 hPa. The parent acid would also be expected to undergo thermal decomposition.

In secondary sources to which reliability could not be assigned, boiling point values of >100°C and 105°C with a decomposition temperature of >200°C after evaporation of water were reported for aqueous solutions of HEBMP-H.
