Preliminary test
Through the serial volume addition of water to the test item, it was shown that the water solubility of the test item was estimated between 500 and 1000 mg/L at 20 °C.

The following concentrations were obtained in the solutions prepared for the hydrosolubility determination.

The mean concentration in silicate is equal to 308 mg/L with an RSD of 0.97%. As the RSD is lower than 15%, the result is acceptable.

 

Conclusions:
Interpretation of results (migrated information): moderately soluble (100-1000 mg/L)
the solubility in water of tetramethylthiuram monosulphide is equal to 308 mg/L at 20°C ± 1 °C.
Executive summary:

The solubility in water of tetramethylthiuram monosulphide was determined in a GLP study according to the OECD 105 guideline. Using the shake-flask method, its solubility is equal to 308 mg/L at 20°C ± 1 °C.
