Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
2-methylundecanal was found to be readily biodegradable under the strict testing conditions of the OECD 301F guideline. In addition, at the concentration used in the test (100 mg/L), it is not inhibitory to micro-organisms.
Further biotic degradation testing such as simulation tests in surface water, sediment and soil is waived. Since 2-methylundecanal is readily biodegradable simulation tests will provide little additional information as rapid mineralisation in the environment is already assumed. Moreover, the chemical safety assessment according to Annex I gives safe risk characterisation ratios at the regional scale and therefore half-life data from simulation tests is not required to further refine the environmental risk assessment.
Assessment of hydrolytic stability was not performed as 2-methylundecanal is readily biodegradable and as such, according to Regulation (EC) 1907/2006, it is unnecessary to investigate hydrolysis as a function of pH.
Information on phototransformation in air, water and soil is not available. It is not a standard information requirement under REACH.
The Koc for 2-methylundecanal was determined to be 3981 according to an OECD 121 study.
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.
