Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Hydrolysis
The Hydrolysis rate constant of 1-chloro-3-nitrobenzene is estimated to be 0.0000000000001199 cm3/molecule-sec at half-life of 1070928hrs. The estimated half-life of the substance indicates that the substance 1-chloro-3-nitrobenzene is negligible hydrolysable.
Biodegradation in water: screening tests
The screening test inherent to the biodegradability of the substance was calculated using the software BIOWIN v4.10.
The results indicate that 1-chloro-3-nitrobenzene is not expected to be readily biodegradable.
Biodegradation in water: screening tests
Half life period of 1-chloro-3-nitrobenzene in water is observed to be 37.5 days (900 hrs.) while in sediment it is 337.5 days (8100 hrs). Based on these half life values of 1-chloro-3-nitrobenzene, it is concluded that the chemical is not persistent in water and sediment.
Biodegradation in soil
EPI Suite has estimated that 1-chloro-3-nitrobenzene is expected to be found not predominantly in soil and its not persistence estimate is based on its transformation in this medium. Its half-life in soil, 75 days (1800 hrs), does not exceeds the threshold of 120 days as per Annex XIII of REACH.
Therefore, 1-chloro-3-nitrobenzene is estimated to be not persistent in the soil environment.
Bioaccumulation: aquatic / sediment
The estimated bioconcentration factor (BCF) for 1-chloro-3-nitrobenzene is 19.5 L/kg, that does not exceed the bioconcentration threshold of 2000. Thus it is concluded that 1-chloro-3-nitrobenzene is not expected to bioaccumulate in the food chain because it does not exceed the BCF criteria.
Adsorption / desorption
The soil adsorption coefficient (Koc) value of 1-chloro-3-nitrobenzene is estimated to be 363.5 L/kg, indicating that it is has a high sorption to soil and sediment and therefore have moderately migration potential to groundwater.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
