Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

RS-Freetext:
Fenitrothion was completely degraded within 50 minutes. For the  degradation of DMP, no specific compound was measured. However, the  formation of phosphate was observed, and the intermediate occurrance of  formate. 
The mass spectrum of DMP is not depicted as was done with other spectra  in the publication. It is (incompletely) reported to have peaks (m/z) at  79, 80, 47, 29, 95, 66, 109, and 110. Intensities were not reported. 
It was stated that DMP occured as an intermediate of complete  fenitrothion mineralization.

Degradation in % (for indirect photolysis): > 70  after 150 minute(s)
