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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Biodegradation:
Inherently biodegradable (WoE, OECD 302 B, OECD 301 D)
Transport and distribution / Bioaccumulation
Adsorption / desorption and bioaccumulation potential is expected to be low (log Kow < 3).
Additional information
Weigth-of-evidence from two reliable studies on inherent biodegradation and one study on ready biodegradation consistently shows that that 2 - chlorobenzaldehyde is (at least) inherently biodegradable. With respect to environmental transport and distribution, information on adsorption/desorption is the only information required for substances up to 100 t/a. According to Annex VIII (section 9.3.1) of Regulation (EC) No 1907/2006, adsorption/desorption screening is not required if the substance has a "low octanol water partition coefficient". Respective criteria in the "Guidance on information requirements and chemical safety assessment - Chapter R.7a: Endpoint specific guidance" (May 2008) are met by o-chlorobenzaldehyd. Asoprtion/desorption testing therefore is not considered necessary.
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.
