Results

For the reference material, anisic acid, the average determined melting point of 183.4 °C was in good agreement with the literature value of 183.0 °C, quoted by the manufacturer.

The melting range of the test substance is, therefore, 168.7 °C to 169.4 °C (= 441.9 K to 442.6 K).

The accuracy of the determination was estimated to be about ± 0.4 °C

Conclusions:

The melting range of the test substance was determined to be 168.7 °C to 169.4 °C (= 441.9 K to 442.6 K).

Executive summary:

The melting point of the test substance was determined according to OECD TG 102 following GLP principles. The determinations were performed using the capillary method. The melting point and the beginning and the final stages of melting were automatically registered using photocell detection. A Mettler FP90 processor and a MBC cell were used in accordance with the manufacture's operating. For the reference material, anisic acid, the average determined melting point of 183.4 was in good agreement with the literature value of 183.0 °C, quoted by the manufacturer.

The melting range of the test substance is, therefore, 168.7 °C to 169.4 °C (= 441.9 K to 442.6 K). The accuracy of the determination was estimated to be about ± 0.4 °C.
