Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Monochloroacetic acid: supporting studies: monitoring data from several publications. Monochloroacetic acid concentrations have been determined in the aquatic compartment, including snow, surface water and rain water.
The concentration of the substance in air has also been determined. On the atmosphere data, Frank (2001) concluded the following: “The results indicate that monochloroacetic acid is an ubiquitous atmospheric component. The atmospheric burden of air masses at remote locations are in the same range, or even higher, than those found in samples collected close to densely populated areas. This must be interpreted as an indicator of monochloroacetic acid being released from non-anthropogenic sources, or as the result of a slow formation from a ubiquitously distributed precursor. However, the fact that the southern hemispheric data tend to be in the same range or higher than northern hemispheric data suggest that 1,1,1,-trichloroethane is unlikely as precursor”.
Concentrations in precipitation tend to be higher than those in surface water. This confirms that atmosphere is an important source of halogenated acetic acids (including monochloroacetic acid) and that precipitation is most likely the major transfer mechanism to the biosphere.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
