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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No literature data or test studies were found related to Adsorption/desorption of monochloramine. Furthermore, the instability of monochloramine during an adsorption/desorption study (OECD guideline 106) would make it impossible to determine whether the obtained results are due to low adsorption/desorption or degradation. Moreover during such a study CaCl2 will be used which destroys the substance as the excess of chlorine will increase the Cl2 to N ratio resulting in the transformation of monochloramine into dichloramine, trichloramine or even free Cl and nitrogen gas.
Nevertheless, Holzwarth et al. (1984) studied the behaviour of the substance regarding the atmospheric compartment. A Henry law's constant was determined to be 0.45 (dimensionless). This value was converted and a Henry law's constant of 0.824 Pa.m3/mol at 20°C was found. Thus it can be concluded that monochloramine presents a volatilisation potential and might be released in the atmospheric compartment.
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.
