vapour pressure
Type of information:
read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: analogue substance
Justification for type of information:
Determination of vapour pressure is not required because available data indicate that structural variation does not influence test results or adverse effect profile (see read-across and category justifications attached in Section 13).
Reason / purpose:
read-across source
Key result
Temp.:
25 °C
Vapour pressure:
0 Pa
