Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The registered compound is expected to show a fast hydrolysis under environmental conditions. The calculated half-life of the registered substance is 4.0 h at pH 7 and 20-25 °C (QSAR). Therefore, hydrolysis is a relevant pathway for the degradation of the parent compound in the environment. The resulting hydrolysis products are methanol and 3-(N-butylamino)propylsilanetriol. Photolysis can be expected to contribute to the overall degradation of N-[3-(Trimethoxysilyl)propyl]-1-butanamine (CAS No. 31024-56-3) and its silanol hydrolysis product in air. If emitted into the air, it will rapidly photodegrade (estimated half-life for indirect photodegradation: 0.17 d, OH-radicals (parent) and 0.16 d, OH-radicals (silanol HP)). However, the substance and its silanol hydrolysis product both have a low vapour pressure and therefore air is not a relevant compartment for the distribution of the registered compound and its silanol hydrolysis product.
