Applicant's summary and conclusion

Conclusions:
1.295E-08 Pa*m3/mol estimated by calculation
Executive summary:

A Henry's Law constant of 1.295E-08 Pa*m3/mol was calculated for the test substance from measured vapour pressure (0.000049 Pa) and solubility (568 g/L) values and molecular weight (150.13 g/mol) using EQUATION R.16-4 (Henry = (VP*MW)/Solubility) in the REACH guidance R.16.
