Description of key information
The test substance is a white solid with a slight sulphur odor. A melting point of 79.5°C was determined using method CIPAC MT 2 according to OECD Guideline 102, EEC guideline A.1, and EPA OPPTS guideline 830.7200. A boiling point of 186°C was determined per Siwoloboff method according to OECD Guideline 103, EEC guideline A.2, and EPA OPPTS guideline 830.7220. The density of 1.3074 g/mL at 20°C was determined using method CIPAC MT 3 in accordance with OECD Guideline 109, EEC guideline A.2, and EPA OPPTS guideline 830.7300. The vapour pressure, 1.91 ×10-4Pa at 20°C, was determined using the gas saturation method in accordance with OECD Guideline 104, EEC guideline A.4, and EPA OPPTS guideline 830.7950. The mean log partition coefficient (log Pow) of 0.11±0.03 at 25.2°C was determined using the shake-flask method according to OECD Guideline 107, EEC guideline A.8, and EPA OPPTS guideline 830.7550. Water solubility of 54.92 g/L at 20°C was determined using the shake flask method according to OECD Guideline 105, EEC guideline A.6, and EPA OPPTS guideline 830.7840. The surface tension of a 1 mg/mL aqueous solution the test substance was determined, according to OECD Method 115, to be 73.7 mN/m at 20.1 degrees C. The test substance was not highly flammable in a test per EEC guidelines A.10. No autoflammability was detected upon heating the test material to 110°C in an auto-flammability test conducted according to EC Method A.16. The test substance was not explosive in a series of tests conducted according to EC Method A14 and is not oxidising based on results from a study conducted according to EPA method 63-14. A 1% solution of the test substance has a pH of 6.84 at 25°C. The test substance was non-ionizable and did not have any acidic or basic properties when tested according to EPA method 63 -10. The particle size assessment (d50) was conducted according to OECD 110, OPPTS 830.7250, CIPAC MT 187, and ISO 13320 and the d50 was 940 µm. This value was also referred to as the Mass Median Diameter (MMD).
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
