CAS number: 34708-08-2
[triethoxy(3-thiocyanatopropyl)silane]: 0.011 Pa at 25°C (QSAR)
[(3-thiocyanatopropyl)silanetriol]: 2.0E-06 Pa at 25°C (QSAR)
Vapour pressure [ethanol]:
7910 Pa at 25°C
A predicted vapour pressure of
0.011 Pa at 25°C was determined for the registered substance using a
validated QSAR estimation method; the result is considered to be
reliable and is selected as key study. The QSAR value has been validated
using reliable measurements for structural analogues reflecting the main
constituent in the registered substance.
In the other available secondary
source to which no reliability could be assigned, a vapour pressure of
<1 hPa at 20°C was reported for the substance.
CAS 34708-08-2; EC No. 252-161-3 hydrolyses moderately in contact with
water to form (3-thiocyanatopropyl)silanetriol and ethanol, CAS 64-17-5;
EC No. 200-578-6.
The vapour pressure of the silanol
hydrolysis product, (3-thiocyanatopropyl)silanetriol was determined to
be 2.0E-06 Pa at 25°C using a validated QSAR estimation method.
Ethanol has a reported vapour
pressure of 7910 Pa at 25°C (Daubert, T E and Danner R P (1985))
