Applicant's summary and conclusion

Conclusions:
The vapor pressure of the substance is 186.6 Pa at 21.1. degrees C.
Executive summary:

The vapor pressure of the test substance was determined in an OECD Guideline 104 study.  The test substance was placed in a stainless steel container, vacuum pumped to 0.0 mm Hg, and then warmed to a certain temperature.  The vapor pressure was then determined at 10, 21.1, 50, and 80 degrees C.  At 80 degrees C, no steady pressure was achieved most likely due to decomposition.  The vapor pressure at 21.1. degrees C was 186.6 Pa.
