Description of key information
The substance is a white, crystalline solid with a pungent odour; EPA OPPTS 830.6302, EPA OPPTS 830.6304 and visual observation; Horn (1990), Nelson (2006) & Macdonald et al. (1985).
Key value for chemical safety assessment
- Physical state at 20°C and 1013 hPa:
- solid
Additional information
Three studies are available to address the endpoint on a weight of evidence approach, outlining the appearance, physical state, colour and odour of the substance.
In the study reported by Horn (1990), the substance was described to be a solid when observed at 20 °C. The study was assigned a reliability score of 2 in line with the criteria of Klimisch et al. (1997).
In the study reported by Nelson (2006), the colour and the odour of the test material were determined in line with the methods outlined in the standardised guidelines EPA OPPTS 830.6302 and EPA OPPTS 830.6304, respectively. Under the conditions of the study, the test material was determined to be white in colour with a pungent odour. The study was assigned a reliability score of 1 in line with the criteria of Klimisch et al. (1997).
In the study reported by Macdonald et al. (1985), the test material was described as a white crystalline solid. The study was assigned a reliability score of 2 in line with the criteria of Klimisch et al. (1997).
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.
