Description of key information

The endpoint is fulfilled using Weight of Evidence. An OECD 236 (FET) study of substance CAS 1271 -19 -8 gave an LC 50 of > 100 mg/L. It was demonstrated that CAS 1271 -19 -8 rapidly hydrolyzes (see 5.1.2).

No endpoints can be estimated with ECOSAR for metal substances, therefore only estimates are given for the organic parts of the chemical structure; Dicyclopentadiene (CAS 77 -73 -6) and Cyclopentadiene (CAS 542 -92 -7). 96h-LC50 are estimated to be 9.765 mg/L and 32.082 mg/L, respectively.

The estimated water solubility limit for the parent substance CAS 1271 -19 -8 is 2.6 mg/L. The FET result is in line with ECOSAR results for the hydrolysis byproducts.
