Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

BUA report:

Irradiation of an aqueous PCA solution with light of wavelengths >290 nm (emission maximum 360 nm) led to a half-life of 7.25 h (Kondo et al., 1988) or to total disappearance of the substance after 6 h (Miller & Crosby, 1983). 4-Chloronitrobenzene and 4-chloronitrosobenzene were detected as primary degradation products. 4-Chloronitrobenzene was stable over the irradiation period of 20 h (Miller & Crosby, 1983). Furthermore, very short half-lives of 2 h (summer, 25 °C) and 4 h (winter, 15 °C) were measured in irradiation model experiments with sterilized natural river water (Hwang et al., 1987).

From this, it can be concluded that PCA in aqueous solutions is rapidly degraded by direct photolysis.
