Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Phototrasformation
As reported in the summary of environmental fate and exposure in HSDB Report of Sulfamethazine (synonym of Sulfadimidine) by Scientific Review Committee, if released to air the substance will exist solely in the particulate phase in the atmosphere. In fact, estimated vapour pressure for Sulfadimidine is in the order of magnitude of 10^-9 mmHg
Sulfadimidine absorbs light at wavelengths > 290 nm (UV max = 297 nm) and therefore may be susceptible to direct photolysis by sunlight.
Hydrolisis
As reported in the summary of environmental fate and exposure in HSDB Report of Sulfamethazine (synonym of Sulfadimidine) by Scientific Review Committee, for this substance hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions.
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.
