If the compounds are sold slightly impure, the melting point range will reflect this fact. The melting point listed in the CRC, Merck Index, or on the MSDS is the melting point of the pure compound. While theoretically these should be constant from source to source, in reality the reported melting points sometimes vary.

Melting point; The melting point of an element or compound means the temperatures at which the solid form of the element or compound is at equilibrium with the liquid form. We usually presume the air pressure to be 1 atmosphere.

A sealed capillary tube is used to take the melting point of a compound that sublimes at or below its melting point. The literature reports the melting point for these compounds accompanied by s, sub, or subl.

We report the development of a robust and general model for the prediction of melting points. It is based on a diverse data set of 4173 compounds and employs a large number of 2D and 3D descriptors to capture molecular physicochemical and other graph-based properties. ... Basic properties, such as the melting-point temperature,

Five linear QSPR models for melting points (MP) of drug-like compounds are developed based on three different packages for molecular descriptor generation and a combined set of all descriptors. A data set of 323 gaseous, liquid, and solid compounds was used for this study. ... Prev. Article Table of Contents...

The maximum temperature allowed for such syringes, 50 °C, practically coincides with the highest melting point of compounds for which the method presented is applicable conveniently. Thus I found 1.01 g cm-3 for I (with some difficulty to keep the temperature everywhere higher than 75 °C), and 0.92 g cm-3 for II.
