Applicant's summary and conclusion

Conclusions:
VP = 17 to 22 kPa
Executive summary:

Depending on information source, the vapor pressure at 25°C is 17 kPa (Handbook of Environmental Data on Organic Chemicals, quoted by IARC Monograph) or 22 kPa (Kirk-Othmer Encyclopedia of Chemical Technology; quoted by HSDB and National Toxicology Program, similar value in SRC PhysProp Database).
