Results and discussion
Melting / freezing point
- Melting / freezing pt.:
- >= 41.3 - <= 68.6 °C
Any other information on results incl. tables
The melting point was determined by Hogg A S (1997) using differential scanning calorimetry, and two distinct peaks were observed in the trace between 41.3 and 68.6°C. It is probable that one peak corresponds to melting of the BDP, while the other corresponds to melting of the impurities.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
