EC number: 252-161-3
CAS number: 34708-08-2
Bioaccumulation: low potential to bioaccumulate based on calculated BCF
of 87 l/kg-ww
A reasonable estimate of bioconcentration factor (BCF) can be obtained
by estimation from log Kow using the method in the Technical
Guidance Document on Risk Assessment (EC 2003, Part III. Chapter 4,
Section 188.8.131.52, Page 37 - 38) using the equation log BCF = 0.85log Kow
- 0.7. The estimated value is BCF = 87 l/kg-ww (log BCF = 1.94) for the
Triethoxy(3-thiocyanatopropyl)silane, CAS 34708-08-2; EC No. 252-161-3
hydrolyses moderately rapidly (half-life of 23 hours at 25°C and pH 7)
to substances which have low log Kow values (< 3) and thus
have low potential for bioaccumulation.
