Additional information

The data provided to address the appearance/physical state/colour endpoint are taken from the public domain. The published handbook entry was assigned a reliability score of 2, in accordance with the guidance document published by ECHA, May 2008, Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance and using the principle for assessing data quality as set out in Klimisch (1997), which instruct that data from a peer reviewed database where the information of the peer review process is available, may be considered reliable with restriction. The origin and quality of available data sheet and product specification data could not be assessed, the data was therefore assigned a reliability score of 4 (not assignable) using the principle for assessing data quality as set out in Klimisch (1997). The appearance/physical state/colour of (R)-2,2,3-trimethylcyclopent-3-ene-1-acetaldehyde was reported as a clear, colourless liquid with a sweet-woody/camphene odour.
