Additional information

The physical state of the test material at room temperature has been addressed on a weight of evidence basis using two GLP compliant study reports. Denton (1994) reports the test material to be a white crystalline powder at room temperature and Baltussen (2012) reports the test material as a white powder at room temperature. Both studies were performed to GLP and in line with relevant test guidelines and have therefore both been assigned a reliability score of 1 according to the principles for assessing data quality set out in Klimisch (1997).
