Description of key information

In accordance with column 2 of REACH Annex VII, the study does not need to be conducted as the substance is hydrolytically unstable (half-life 7.3 hours). 
Auxiliary, the water solubility for 1-chloro-4-isocyanatobenzene was calculated by the means of WSKOW program of the EPI-Suite software yielding a value of 158.4 mg/L at 25 °C (Bayer Industry Services, 2004). This value is only of theoretical interest since the program does not consider the rapid hydrolysis of the substance.
was estimated by the means of WSKOW program based on an experimental logKow of 3.12 (Bayer Industry Services, 2004). The rapid hydrolysis of the test substance is neglected.
