- Expiration date of the lot/batch: May 2017
- Purity test date: 30.01.2017
STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: at room temperature
- Stability under test conditions: stable - Key result
- Melting / freezing pt.:
- 115.6 °C
- Atm. press.:
- 1 013 hPa
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- Using a linear heating rate of 0.5 °C/min, the melting point of 3-Tert Butyladipic Acid was determined to be 115.6 °C (388.7 K).
- Executive summary:
The melting point of the test substance was determined by the capillary method according to OECD guideline 102 (TOXICOOP, 2017). A small amount of test item was charged in capillary glass tubes with a diameter of about 2 mm and packed tightly to obtain a filling level of approximately 5 mm. Three capillaries were heated in the oven of the melting point device. Heating was started from 106 °C. Temperature rise was adjusted to 0.5 °C/min. Melting of the test item was detected automatically by the photosensors.
Applying 0.5 °C/min heating rate, the melting point of the test substance was determined to be 115.6 °C (388.7 K).
