Considering the water solubility for 48 hrs and 72 hrs the mean water solubility was calculated as follows:

Mean water solubility value for 48 hour run sample + 72 hour run sample

=(3616.96+2877.56)/2

=3247.26 mg/L

Conclusions:
The water solubility determination of test item Tetrabutylammonium iodide (CAS No.311-28-4) was done by spectrophotometric method. The water solubility was determined to be 3247.26 mg/L at 28°C.
Executive summary:

The water solubility determination of test item Tetrabutylammonium iodide (CAS No. 311-28-4) was done as per the OECD guideline 105 and by spectrophotometric analytical method as per OECD 101. The water solubility was determined to be 3247.26 mg/L at 28°C.

Additional information

The water solubility determination of test item Tetrabutylammonium iodide (CAS No. 311-28-4) was done as per the OECD guideline 105 and by spectrophotometric analytical method as per OECD 101. The water solubility was determined to be 3247.26 mg/L at 28°C.

Data from authoritative database indicates that tetrabutylammonium bromide was slightly soluble in water at 20degC.

Data from authoritative databases suggest that the estimated water solubility of Tetrabutylammonium bromide at 25 deg C was 163.2 mg/l.

These values indicate that Tetrabutylammonium iodide can be considered soluble in water.
