- Key result
- Melting / freezing pt.:
- < -70 °C
- Conclusions:
- Freezing Point evaluated by DSC to be as follows:
Purified Active Below -70.0 °C (203.2 K)
Technical Active Below -70.0 °C (203.2 K) - Executive summary:
An experimental study was conducted similar to Regulation (EC) No 440/2008 Method A.1. and OPPTS 830.7200 to determine the freezing range of the test items. The freezing point is defined as the temperature at which the phase transition from liquid to solid state takes place. Ther differential scanning calorimeter methode was used STARe version 6.01 software was used for all determinations. The instrument was calibrated using an Indium reference standard before use. Air was used to purge the instrument and the measuring cells. Test scans were made against an empty aluminium pan as the reference sample. A sample between 7 and 8 mg of both test substances (Purified Active and Technical Active) was weighted into an aluminium DSC pan (40 uL). The pans were then sealed with pierced aluminium lids and scanned before defined temperature programs (initial and definitve). The freezing temperature for both Test substances was Below -70.0 °C (203.2 K).
