Additional information
Short-term toxicity to fish (oryzias latipes); 96 h-LC50 = 0.380 mg/L; 96 h-NOEC = 0.327 mg/L
Short-term toxicity to aquatic invertebrates (daphnids); 48 h-EC50 = 1.4 mg/L; 48 h-NOEC = 0.12 mg/L
Toxicity to aquatic algae (selenastrum capricornutum); 96 h-EC50 = 0.93 mg/L; 96 h-NOEC < 0.49 mg/L
Conclusion on classification
The substance is classified as the acute toxicity category 1 (acute EC50 <1 mg/l).
The substance is rapidly degraded by hydrolysis to maleic acid (CAS No.108 -31 -6) and aniline (CAS No.62 -53 -3)
whose substances are known to be rapidly biodegradable (see chapter 5.2.1). And the log Pow of the substance is <4 (1.16).
Therefore, the substance is not classified in the chronic aquatic category.
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.
