Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

vapour pressure
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the melting point is above 300°C

Description of key information

The melting point of zinc cyanide is 800°C, which is a substance that melts at over 300°C. According to the column 2 of the annex VII section 7.5 of Regulation (EC) No 1907/2006 concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), the study does not need to be conducted if the melting point is above 300°C.

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
25 °C

Additional information

To be able to run the CSA, a value for VP is needed. As the key value for CSA purposes, the minimal value accepted by CHESAR is set, i.e. 1E-06 Pa.

Indeed, QSAR models (EPISuite v4.1) predict VP values < 1E-06 Pa.
