Which compound has a melting point of approx #134^@#C or #135^@#C? I don't know whether the melting points taken by me in the lab are correct. Is there any way to find if the M.P is correct?

The usual advice is to recrystallize to constant melting point.


That is the take the melting point of the crude material; recrystallize it, dry it, take the melting point again; is it the same as the first? If no, recrystallize again (small samples each time). If your melting points are consistent, your melting points are probably correct.
