EC number: 205-746-2 | CAS number: 149-74-6
Bioaccumulation: aquatic / sediment
Administrative data
Link to relevant study record(s)
- Endpoint:
- bioaccumulation in aquatic species: fish
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance has a low potential for bioaccumulation based on log Kow <=3 and a low potential to cross biological membranes
Reference
Description of key information
Bioaccumulation: aquatic/sediment: Low potential for bioaccumulation
Key value for chemical safety assessment
Additional information
The substance hydrolyses very rapidly to form methylphenylsilanediol and hydrochloric acid. The silanol hydrolysis product, has low log Kow values (<3) and thus low potential for bioaccumulation, and the requirement for testing is waived. The other hydrolysis product is hydrochloric acid, which is an inorganic substance and bioaccumulation is not relevant.
