Description of key information
The substance is a UVCB of organic origin. It is a liquid at room temperature with a transparent, brownish colour and an extremely strong, pungent odour, which is earthy and solvent like. The relative density of the liquid is 0.934. The freezing temperature is less than -20 °C and the boiling temperature is 154 °C. The pH value of a 1% (w/v) aqueous solution of the substance is 9.1 at 25 °C. The kinematic viscosity of the liquid was determined to be 0.799 mm2/s at 40 °C. The surface tension was determined to be 69.7 mN/m at 20 °C.
The vapour pressure of the substance is 453 Pa at 20 °C. The water solubility of the substance at 20 °C is at least 501 g/L and the log Kow value of the substance is in the range from 1.09 to 2.08. A water solubility of 501 g/L at 20 °C and a log Kow value of 2.08 will be used in the chemical safety assessment of the substance.
The flash point of the substance was 45 °C. The substance did not release flammable gases on contact with water and did not ignite spontaneously on contact with air. The autoflammability was determined to be 540 °C. The heat of decomposition, as determined with an appropriate DSC method, was 90 J/g, which is clearly below the cut-off values for self-reaction (300 J/g) and explosive properties (500 J/g). Based on the absence of oxygen, chlorine or fluorine in the chemical structure, the substance is assessed to be non-oxidising.
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.
