Description of key information

The toxicity of N2-Isobutyryl-5’-O-(4,4’-Dimethoxytrityl)-2’-deoxyguanosine was tested according to OECD guidelines 201 and 202 for acute toxicity studies with aquatic invertebrates (Daphnia magna) and algae (Pseudokirchneriella subcapitata). No toxic effect on P. subcapitata was observed up to the limit of water solubility (NOEC ≥ 100 mg/L nominal, corresponding to 4.92 mg/L measured). For D. magna a 48 h EC50 of 8.291 mg/L was determined.
