Conclusions:
On the basis of effects observed in a static freshwater system, the NOEC value for the substance is estimated to be 397.33 mg/l for fish for 28 days of exposure duration
Executive summary:

Based on the prediction done using ECOSAR version 1.1, the long term toxicity on fish was predicted for test substance . On the basis of effects observed in a static freshwater system, the NOEC value for the substance Tributylmethylammonium chloride ( 56375-79-2) is estimated to be 397.33 mg/l for fish for 28 days of exposure duration.It can be concluded that the test chemical Tributylmethylammonium chloride(56375-79-2 ) can be considered as non-toxic to fish at environmentally relevant concentrations and can be considered not-classified as per the CLP classification criteria.
