- SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: SOAP012-2
- Expiration date of the lot/batch: 01 November 2022
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Ambient. - Melting / freezing pt.:
- >= 193 - <= 201 °C
- Atm. press.:
- 1.013 Bar
- Decomposition:
- no
- Remarks on result:
- other: Pressure not stated, therefore assumed standard
- Conclusions:
- The melting point of the test item was determined to be 193 - 201°C.
- Executive summary:
The melting point of the test item was determined in an experimental study conducted according to the OECD 102 guideline (Dunning 2018). The melting temperature was determined by the metal block method using a calibrated digital melting point apparatus. The definitive test was conducted in duplicate. The melting point of the test item was determined to be 193 - 201°C.
The study is GLP-compliant and was conducted according to the standard guideline, therefore is considered reliable without restrictions and suitable as a key study for this endpoint.
