Description of key information

The stability of 1-chloro-4-isocyanatobenzene under conditions simulating those in the environment was tested meaning a pH of 7 as well as the presence of air and light. The test substance was dissolved in a buffer solution and subsequently keept at a temperature of 25 °C and ilumination. Samples were periodically taken and measured by the means of HPLC. Over the test duration of 70 h, the concentration of the test substance continuously decreased yielding a half-live of 7.3 h. 1-amino-4-chlorobenzene was identified as the only hydrolysis product (Bayer Industry Services, 2004).
