Description of key information
The water solubility of di(morpholin-4-yl) disulphide (DTDM) was evaluated in a study performed in accordance with OECD testing guideline 105 and GLP requirements. The flask method was used. During the analysis,the temperature was 20.2°Cand the mean value of pH was 8.91.
DTDM can be considered as moderately soluble (100 - 1000 mg/l)
Key value for chemical safety assessment
- Water solubility:
- 215 mg/L
- at the temperature of:
- 20.2 °C
Additional information
The water solubility of di(morpholin-4-yl) disulphide (DTDM) was evaluated in a study performed in accordance with OECD testing guideline 105 and GLP requirements. The flask method was used.
During the analysis, temperature was 20.2°Cand the mean value of pH was 8.91.
The values of the replicates are reported below
Test T24 h Test T48 h Test T72 h |
8.78 8.89 9.06 |
0.11 0.215 0.13 |
The results obtained show that results measured in the 2 last vessels differ by more than 15 %.
This unusual situation may be due to the hydrolysis of the test item, as the known half-life is less than one day.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
