This is the raw data documenting the influence of the alkyl chain length in 3 position on the toxicity to the promyelocytic leukemia rat cell line IPC-81. The substances are named according to the UFT naming scheme of these substances. IM13 BF4 means 1-methyl-3-propylimidazolium tetrafluoroborate, IM14 BF4 means 1-methyl-3-butylimidazolium tetrafluoroborate and IM1-10 BF4 means 1-methyl-3-decylimidazolium tetrafluoroborate. This is a subset (only the BF4 anion) of the data shown in Figure 3 in Ranke et al. (2004).

Format

A dataframe containing the data as required for the drfit function. An additional column contains the tested organism (name of the cell line).
