Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

According to OECD Guideline 301 B (Ready Biodegradability: CO2 Evolution Test), the test substance is readily biodegradable.

The general experience is that a substance passing a test for ready biodegradability may under most environmental conditions be rapidly degraded, therefore phototransformation in sediment and soil is considered to be not a relevant environmental degradation mechanism. The calculated (QSAR AOPWIN) half life by phototransfromation in air for 1,4 diaminobutane is approximately 2 hours. Based on this information rapid degradation in the environment is expected.
