solid

Additional information

The appearance of the test material was recorded as a visual inspection performed as part of the routine procedure while conducting melting point study Calmels (1995) which was performed under GLP conditions. The substance was reported to be an orange powder at room temperature.

As the study was performed under GLP conditions and to standardised guidelines for the determination of the melting point, it is considered that the recorded visual observations of the test are an accurate reflection of the substance. Although the appearance and physical state of the substance were not the main focus of the study, the data is considered to be reliable and was therefore assigned a reliability score of 2, in line with the principles for assessing data quality as defined in Klimisch et al (1997).
