The initial stages of melting, as referenced in OECD Method 102, were indistinct.
Differential scanning calorimetry (DSC)
The DSC trace showed a sharp endotherm at approximately 64°C, consistent with the melting temperature observed in the metal block test.
Applicant's summary and conclusion
- Conclusions:
- The melting range of WS-23 was found to be 62 to 64°C.
- Executive summary:
The melting temperature of WS-23 was determined using the metal block method (according to OECD TG 102). The melting range of WS-23 was found to be 62 to 64°C.
