Conclusions:
Based on nominal concentrations, experimental median lethal Concentrations [LC-50 (96 h)] for CAS No 65122-06-7 on Zebra fish(Danio rerio)was found to be 12.5 mg/L.
Executive summary:

Fish Acute Toxicity test according to OECD Guideline 203 was conducted for Reaction mass of 3H-Indolium, 2-[2-[4-[(2-cyanoethyl)methylamino] phenyl]ethenyl]-1,3,3-trimethyl- & acetate on Zebra fish.

The nominal concentration selected for the experiment were 6.25mg/L,12.5mg/L,25mg/L,50mg/L,100mg/L andZebra FishDanio rerio were exposed to these concentration for 96 hours.

 

The test substance was soluble in water. Therefore, the test solution was prepared by dissolving 1 g of the test substance in 1 liters of potable water (passed through reverse osmosis system) with continuous 1 hr stirring,After stirring stock was analytically detected ,the solubility found 848.46 mg/L.

Bowl aquaria containing 2 liters of potable water (passed through reverse osmosis system) were loaded with 8 fishes. A static procedure was used for the study and it was conducted in compliance with the OECD guideline 203.

The nominal concentration selected for the experiment were 6.25mg/L,12.5mg/L,25mg/L,50mg/L,100mg/L ,respectively and Zebra fish were exposed to this concentration for 96 hours. The lethal concentrations LC50 was found to be 12.5 mg/l

After 96 hours of exposure to test item Reaction mass of 3H-Indolium, 2-[2-[4-[(2-cyanoethyl)methylamino] phenyl]ethenyl]-1,3,3-trimethyl- & acetate to various nominal test concentrations, LC50 was determine to be 12.5 mg/l . Based on the LC50, it can be consider that the chemical was toxic and can be consider to be classified as "Acute aquatic 2" as per the CLP classification criteria.
