Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Additional information

A hydrolysis constant of 5.0 x 10-6 per hours (pH 7-9, 25°C) with a calculated half-life of 15.8 yr, has been derived for 1,2-dichloropropane in water (MacKayet al., 1993). Therefore the substance shows a very good stability in water as it is not subject to any abiotic degradation (hydrolysis), unless in a very long time.

1,2-Dichloropropane does not have any chromophore groups that absorb wavelengths >290 nm, so direct photolysis will not be a significant fate process.
