Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information

Experimental data on the biodegradation potential of (1R,2S)-2,6-dimethyl-2,3-dihydro-1H-inden-1-amine (CAS 752984-24-0) are not available. Therefore, the assessment is based on experimental read-across data available for the structurally analogous substance (1R,2S)-2,3-Dihydro-2,6-dimethyl-1H-inden-1-amine hydrochloride (CAS 730980-53-7).

The biodegradation potential of the source chemical was investigated in a GLP compliant Manometric Respirometry Test performed according to EU-method C.4-D using predominantly domestic, non-adapted sewage as inoculum. The substance was found to be not readily biodegradable over the test period (0 % biodegradation after 28 days).

Based on the available read-across data, the target substance 1R,2S)-2,6-dimethyl-2,3-dihydro-1H-inden-1-amine (CAS 752984-24-0) is considered to be not readily biodegradable (according to OECD criteria).
