TLC is the quickest and easiest way to check purity.
A sharp mp of an known organic solid is another important method.

Melting point. It is EXTREMELY sensitive. For more information, see:

You ever watch the movie "The French Connection"? What the guy with the switchblade does after cutting open a key of heroin, is determine the melting point.
I doubt he was capable of any more sophisticated measures of chemical purity than that.

I think it is the melting point.
There will be a difference in the melting point from theoritical prediction if the compound is not pure.

yeah, like the others said NMR - melting point and mixed melting point would be the right way 2 check

melting point
This is the simplest method.
