Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Type of information:
(Q)SAR
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
Justification for type of information:
Please refer to attached justification documents

2.7 E-09 Pa

Conclusions:
A vapour pressure value of 2.7E-09 Pa at 25°C was obtained for DTPMP-H using a relevant calculation method. The result is considered to be reliable.

Description of key information

Vapour pressure (DTPMP-H): 2.7E-09 Pa at 25°C (QSAR)

Key value for chemical safety assessment

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

Additional information

A predicted vapour pressure of 2.7E-09 Pa at 25°C was obtained for DTPMP-H using accepted calculation method (MPBPVP program, USEPA/Syracuse Research, v1.43). The result (Fisk 2010) is considered to be reliable as a key study. This value represents the major constituent only and demonstrates that it is involatile.
