Description of key information

This one-to-one read across uses data generated for a chemical similar compound. For this compound information is available from a study that was performed according to GLP and to OECD TG 202 study, giving a NOEC of > 100 mg/L (nominal). Thus no toxicological effect occurs up to the limit of water solubility.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
100 mg/L

Additional information

For this endpoint information from a GLP compliant OECD TG 202 study is available. The data were obtained for a chemical similar compound and used in a one-to-one read across.

Justification for read across

Type of read across: one-to-one

Based on:

(1) chemical similarity: both compounds share a bicyclohexyl core structure and differ in alkyl substitution pattern

(2) almost identical physicochemical profile

(3) same response in relevant biological assays
