Applicant's summary and conclusion

Conclusions:
The melting point of Difluorosulfonamide HCl was measured by the Capillary Melting-point Apparatus. The melting point of the test material was determined parallel 2 times. Based on the results, the average onset point of Difluorosulfonamide HCl was 179.2°C, the average clear point was 180.3°C and the averaging melting range was 1.2°C.
Executive summary:

Based on the results, the average onset point of Difluorosulfonamide HCl was 179.2 °C , the average clear point was 180.3 °C and the averaging melting range was 1.2 degrees °C.
