Additional information

Following studies of target chemical includes data from prediction model and Authoritative database to conclude the toxicity extent of 4-Chloro-1-methylpiperidinium chloride (CAS: 5382-23-0) is summarized as follows:

On the basis of EPI suite, ECOSAR version 1.1, the LC50 value for short term toxicity to fish was predicted to be 261.626 mg/l for 4-chloro-1-methylpiperidinium chloride in 96 hrs. Based on the LC50 value, it can be concluded that the substance 4-chloro-1-methylpiperidinium chloride as not toxic to aquatic environment and thus can be considered“not classified”per the CLP criteria.

Similar predicted data from Danish QSAR database indicates that the estimated 96 hrs LC50 value of 4-Chloro-1-methylpiperidinium chloride(CAS: 5382-23-0) on Fathead minnow by three different models i.e, Battery, Leadscope and SciQSAR used within Danish QSAR database is 133.89 mg/L. It can be concluded from the estimated value that the 4-Chloro-1-methylpiperidinium chloride (CAS: 5382-23-0) is not toxic to aquatic environment and can be considered as "not classified" as per CLP regulation.

Thus based on the effect concentrations which is in the range 133.89 mg/L mg/l to 261.626 give the conclusion that test substance 4-Chloro-1-methylpiperidinium chloride (CAS: 5382-23-0) was likely to be not toxic to fish at environmentally relevant concentrations and can be considered to be“not classified”as per the CLP classification criteria.
