Purification Is Essential

Why would a chemist measure the melting point of a chemical sample?

The melting point of a compound can provide information on whether it is pure and about whether the correct compound has been made. This, of course, assumes that the melting point of the desired compound is already known. If a compound is being made for the first time, knowledge of the melting point can be useful to the next chemist who tries to synthesize it.
