Additional information
The appearance of the test substance was determined in two studies. The test substance has been determined to be white to yellow in colour, by visual assessment, at ambient temperature. The substance was found to be a low melting point solid which forms a liquid at temperatures above its freezing point of 20.8 °C (294 K) with an odour defined as faintly mercaptan-like.
