Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The key ecotoxicity values selected for the registered substance are as follow, in accordance with required data for the tonnage band 1-10 tons per year:
- Aquatic Invertebrates: 48-h EL50 = 0.317 mg test material/L (lowest acute E(L)C50 value)
- Algae: 72-h ErL50 = 2.14 mg test material/L (growth rate).
Those key values have been extrapolated to the registered substance from experimental valid studies performed according to OECD guidelines and under GLP conditions on another alkyl nitrite substance (isoamyl nitrite), following a read-across approach.
Based on these results, the lowest acute E(L)C50 is below 1 mg/L.
Additional information
CLP Classification proposal
It is proposed to compare submission substance dataset to CLP environmental criteria laid down in CLP Regulation:
- Acute aquatic hazard: category 1. Reasoning: lowest E(L)C50 < 1 mg/L (aquatic invertebrates).
- Chronic aquatic hazard: not classified. Reasoning: adequate chronic toxicity data are not available, lowest acute E(L)C50 value is between 0.1 and 1 mg/L, rapidly degradable substance with Log Kow < 4.
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.
