A measured volume of the sample was then injected upon a disc of filter paper suspended in each chamber. (The sample was seen to evaporate completely within 20 seconds). The mice were observed continuously during an exposure period of one hour and suviving animals were observed for 11 days.

- Executive summary:
5 males of wbs/s MICE 527+/- g BW were placed in each of a series of 20-litter exposure chambers and the latter sealed airtight. A measured volume of the sample was then injected upon a disc of filter paper suspended in each chamber. (The sample was seen to evaporate completely within 20 seconds). The mice were observed continuously during an exposure period of one hour and suviving animals were observed for 11 days. The LC 50 was set at 11.2 mg/l (3680 ppm).
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).
