Description of key information
The toxicity to micro organism of the substance 4-chloro-1-methylpiperidine (Cas no. 5570-77-4) to micro organism Tetrahymena pyriformis is predicted using QSAR toolbox version.3.3, based on the effects observed in a static freshwater system during a 48 hr exposure. The Inhibition growth concentration (IGC50) for the substance 4-chloro-1-methylpiperidine is estimated to be 240.91 mg/L.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 240.91 mg/L
Additional information
Predicted data for the target substance 4-chloro-1-methylpiperidine and experimental study for its structurally similar substance has been reviewed for toxicity to microorganism endpoint and are presented below as weight of evidence approach:
The toxicity to micro organism of the substance 4-chloro-1-methylpiperidine (Cas no. 5570-77-4) to micro organism Tetrahymena pyriformis is predicted using QSAR toolbox version.3.3, based on the effects observed in a static freshwater system during a 48 hr exposure. The Inhibition growth concentration (IGC50) for the substance 4-chloro-1-methylpiperidine is estimated to be 240.91 mg/L. Based on this value, it can be concluded that the test chemical 4-chloro-1-methylpiperidine (Cas no. 5570-77-4) may have no concern to micro organism toxicity for acute exposure period.
As per the data available in IUCLID dataset, 2000; Bacterial growth inhibition test of the structurally similar substance N-Methyldiethanolamine (CAS 105-59-9) was carried out as per DIN 38412/8 method. Pseudomonas putida was the bacteria used to measure the effects. The 50% effective concentration i.e. EC50 value of the substance N-Methyldiethanolamine based on growth inhibition to bacteria Pseudomonas putida was determined to be 410 mg/l after 17 hours of exposure.
Thus by applying weight of evidence approach it can be concluded that the substance 4-chloro-1-methylpiperidine is not that toxic to microorganisms.
