Applicant's summary and conclusion
- Conclusions:
- The melting point was observed to be 44.78 °C for AEBP (OECD 102).
- Executive summary:
The melting point range of AEBP was determined using a differential scanning calorimeter apparatus. The study was conducted in accordance with OECD 102 method and was GLP compliant, therefore the study is considered reliable without restrictions.
