Melting points

Melting points are measured (determined) for four reasons:
  1. The melting range and upper limit are an indication of the purity of the sample.
  2. Comparison of the melting point with the literature may indicate the identity of the compound or confirm that it is not the compound required.
  3. If the compound is new, other scientists will need the information.
  4. The compound can be identified with reasonable certainty by taking a mixed melting point.
