We are just Performing Diels-Alder Reaction, and in the product, we get this 1,4-dihydroxytriptycene as per the theory, to confirm our product we want to analyze its melting point.
338-340°c, dec. Reference: Journal of the American Chemical Society (1942), 64, 2649-53
Darkens at 340°, decomposes at 345°; see p. 1684-1685 in

Dear Shubang Vyas many thanks for posting this interesting technical question on RG. There seem to be some discrepancies about the melting point of 1,4-dihydroxytriptycene in the literature. Personally I would trust the data published by Clar et al. (cited by Rouvain Bension). At that time (around 1930) chemists used to be very careful when measuring the melting points of new chemical compounds because they did not have all the modern techniques such as NMR and XRD available. Thus melting points were important data which were taken more seriously than today. Moreover, Erich Clar was a prominent chemist which was well-known as the guru of aromatic hydrocarbon chemistry (cf. the respective Wikipedia entry at https://en.wikipedia.org/wiki/Erich_Clar).
Good luck with your work and best wishes!
