SUMMARY
The melting point of 147ºC (dec.) indicates that the sample decomposed rather than melted, suggesting that the sample may contain reactive impurities. A pure sample should exhibit a clear melting point without decomposition. The presence of decomposition implies that the sample is not 100% pure, as reactive impurities such as strong mineral acids or oxidizers can cause this behavior. Therefore, no definitive conclusions about purity can be drawn without additional information on the expected melting behavior of the analyte.
