Additional information
Terahydrofuran-borane does not need to be clasified for the environment.
Tetrahydrofuran-borane is known to readily hydrolize liberating hydrogen, tetrahydrofuran (CAS 109-99-9) and boric acid (CAS 10043-35-3). The environmental classification for the parent substance is based on the worst case environmental classification of both hydrolysis products.
Tetrahydrofuran is qualified as readily biodegradable. For tetrahydrofuran short-term aquatic toxicity data are available for two trophic levels (fish and aquatic invertebrates) with acute effect concentrations of ≥ 2160 mg/L. In addition, long-term aquatic toxicity data are available for two trophic levels (fish and aquatic algae). Chronic effect concentrations are reported to be ≥216 mg/L. Based on this information, tetrahydrofuran needs not be classified for the environment according to regulation EC/1272/2008 (CLP) or according to directive 67 /5748/EEC (DSD).
Boric acid is qualified as not readily biodegradable. For boric acid short-term and long-term aquatic toxicity data are available for three trophic levels. Acute effect concentrations were found to be ≥ 52.4 mg/L, chronic effect values were found to be ≥3.5 mg/L. Based on this information, boric acid needs not be classified for the environment according to regulation EC/1272/2008 (CLP) or according to directive 67 /5748/EEC (DSD).
Conclusion on classification
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.
