Executive summary:

Introduction

The study was designed to determine the melting point of the test substance. The melting point was determined using a Buchi Melting Point Apparatus B-545.

Results and conclusion

The test material was determined to decompose at 293°C. As the test material decomposed prior to melting, no value for boiling temperature was determined or required.
