At Boiling Point all the material evaporates leaving no residue which means it is pure.
But if it leaves some residue after evaporating at boiling point then it is not pure.
For example : If you take an example of pure water & Saline Water then pure water will evaporate at its boiling point leaving nothing after it.
But Saline water evaporates leaves salt behind it.
pure substances have a distinct boiling point. Adding more heat just makes the substance boil faster but the temperature stays the same. A mixture does not have a distinct boiling point. Adding more heat will make the temperature increase.
take water for example, if water boils at 100 degrees Celsius then it is pure. if the boiling temperature turns out to be higher or lower (most of the time it is higher) then a substance is impure. salt water boils at 102.8 degrees Celsius.
The boiling temperature of a pure substance is unique and specific to that substance. It is determined by its molecular structure and strength of intermolecular forces. This characteristic boiling temperature is referred to as the substance's normal boiling point.
The melting and boiling points of a substance are characteristic physical properties that can be used to assess purity. A pure substance will have a sharp melting or boiling point, occurring at a specific temperature range. Impurities tend to disrupt the orderly arrangement of particles in the substance, leading to a broader or lower melting/boiling point compared to the pure form. By comparing the experimental melting or boiling point of a sample to the literature values for the pure substance, one can determine the level of purity.
Physical properties of a pure substance include color, melting point, boiling point, density, solubility, and conductivity. These properties can be used to identify and characterize the substance.

Each liquid boils at a different temperature, but the temperature it boils at is called the Boiling Point. For example, the boiling point of water is 212 Fahrenheit.This specific temprature is dependant on the pressureon the liquid at that time, as an example at ahigher temperatures the boiling point is higher.

Boiling point is the temperature in which a substance in a liquid state turns to a gas state. In a pure substance (an element or 1 compound) that temperature is a unique property. For example, pure water boils at 100 degrees Celsius. Methanol has a boiling point of 64.7 degrees Celsius. In pure substances the temperature time graph makes a plateau. The boiling point is the same as the condensation point (where a gas turns into a liquid) for that substance.

The melting point and the boiling point of a substance are physical characteristics for each substance and are unchanged at the same pressure.
You can check certain properties, such as density and boiling point.
Boiling point- the temperature and pressure at which a liquid and a gas are in equilibrium. But also, it is very useful in determining the purity of a substance. If the melting point is known of the pure substance, than you can measure the melting point of what you've got and see if it matches. If the melting (or boiling) point is the same, than that is a good indication that the compound you have is what you think it is, and it is pure. If they are different from each other, that indicates that your compound is not pure.
