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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
HLC (silanol hydrolysis product) = 2.49E-10 Pa m3/mol (QSAR)
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0
- at the temperature of:
- 20 °C
Additional information
The transfer of a substance from the water phase to the gas phase can be estimated by means of the Henry’s Law Constant (HLC). No measured value for this parameter is available. The HLC can be estimated from the ratio of the vapour pressure to the water solubility.
HLC = VP x MW/WS
Volatilisation from water is not relevant for N-[3-(trimethoxysilyl) propyl]butylamine due to its rapid hydrolysis in contact with water.
The calculated HLC value for3-(N-butylamino)propylsilanetriol is low, 2.49E-10 Pa m3mol-1(Bond estimation taken from EPIWIN 4.10).
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.
