Description of key information

DTPA-H5 starts to decompose at 206 degrees C.

Key value for chemical safety assessment

Additional information

In accordance with column 2 of Reach Annex VII, vapour pressure testing is not required for chemicals with a standard melting point

of >300ºC. If the melting point is between 200ºCand 300ºC, a limit value based on measurement or a recognised calculation method is sufficient. DTPH-H5 starts to de compose at 206 degrees C. Therefore, based on literature, the vapour pressure of DTPH-5 is considered to be lower than 0.01 mg Hg at 20 degrees C.
