After the heat
Its melting point on the heater was not known, it changes slowly when heated, it is probably also sensitive to humidity. In my opinion, this humidity causes an error in the melting point of the product.
I once poured the product into diethyl ether for solvent-antisolvent extraction after 3 hours of reflux, neutralization, and filtration, and a white precipitate came out, but it didn't even show the reported melting point. I don't know why, but now that I think about it, I think the humidity caused it.
Do you know why?

G.PattonI did it once, I added ether to methanol and it precipitated, its color was almost white, but its melting point was unknown

Have you recrystallized your product? What is the difference in melting point?
