Additional information
Conclusion on classification
Dichloromethyl(3,3,3-trifluoropropyl)silane is expected to hydrolyse rapidly in contact with water tomethyl(3,3,3-trifluoropropyl)silanediol andhydrochloric acid (Half-life estimates were < 17 seconds for pH 4, 7, and 9 at 1.5°C., see Section 4.1.1.1).The substance is not readily biodegradable according to OECD criteria.
Dichloromethyl(3,3,3-trifluoropropyl)silane is classified as Chronic 3 for the environment in the EU according to Regulation (EC) No 1272/2008 because measured data for the parent substance show a EC50/NOEC of > 10 mg/l (EC/LC50values in the 10-100 mg/l) as lowest endpoint and lack of degradability of the hydrolysis product.
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.
