Endpoint summary
Administrative data
Description of key information
Additional information
Appearance
The substance is an amber coloured liquid with no reported odour
Freezing point
The pour point of the test item has been determined to be 9 ± 3°C (282 ± 3 K).
Boiling point
The test item decomposed from approximately 244°C (517 K) at 100.9 kPa.
As the test item decomposed, no value for boiling temperature could be determined.
Density
The relative density of the test item has been determined to be 1.13 at 20.0 ± 0.5°C.
Granulometry
The substance is a liquid.
Vapour pressure
The vapour pressure of the test item has been determined to be 7.6 x 10-2 Pa at 25°C.
Octanol/water partition coefficient
The partition coefficient of the test item has been determined to be greater than 2.51 x 109, log10 Pow >9.4
Water solubility
The water solubility of the test item has been determined to be less than or equal to 1.14 x 10-4 g/l of solution at 20.0 ± 0.5°C.
Surface tension
Water solubility is less than 1 mg/L at 20°C
Flash point/Flammability
The flash point of the test item has been determined to be 57 ± 2°C.
Autoflammability
The test item has been determined to have an auto-ignition temperature of 458 ± 5°C.
Explosiveness
There are no chemical groups associated with explosive properties present in the molecule. The structure of the test material was assessed for chemical groups that imply explosive properties. Examples of such groups are C-C unsaturated, C-metal, N-metal, contiguous oxygen atoms, contiguous nitrogen atoms, N-halogens, O-halogens, N-O.”
Based on the chemical structure of the test item the result for the explosive properties has been predicted negative.
Oxidising properties
The substance is incapable of reacting exothermically with combustible materials on the basis of the chemical structure. The structure of the test material was assessed for chemical groups that would imply oxidising properties. Examples of such groups are nitrates, metal oxides, hypofluorites, difluoroaminopolynitroaryls, perchlorates, bromates and iodites.
Based on the chemical structure the result for the oxidising properties has been predicted negative.
Stability in organic solvents
The test substance is stable as a solution in corn oil for 8 days. Corn oil is suitable for use as a vehicle in the 28-day repeated dose oral toxicity study
Dissociation constant
Predicted values of the dissociation constants for the test item using ACD/Labs I-Lab 2.0 on a structure representative of the test item were -1.58 ± 0.40 and -2.22 ± 0.4 for the saturated nitrogen atom in the thiadiazole ring. Therefore, no dissociation constants were predicted under environmentally relevant conditions (pH 0 to 14).
Viscosity
The viscosity of the test item was 2.86E03 mm2/s at 40°C
