Any other information on results incl. tables

Results:              The determination of the melting point was performed by visual judgement using the capillary method.

The test item showed five stages of melting. The melting started at 43.6 °C. At 50.0 °C the final stage of melting was reached. No solid particles were left.

Conclusion:      In conclusion, the test item N-[3-tris(trimethylsilyloxy)-silylpropyl]prop-2-enamide melted in the range of 44 °C to 50 °C.
