[Chemical Properties]

light yellow to brown crystalline powder
[Uses]

3,4,5-Trimethoxyphenol is a useful synthetic intermediate in the synthesis of Thymonin (T413210); a flavonoid compound with potential antioxidant activity against peroxyl radicals.
[Definition]

ChEBI: A member of the class of phenols that is phenol substituted by methoxy groups at positions 3, 4 and 5.
[Purification Methods]

Recrystallise the phenol from 10 times its weight of H2O (white needles, m 148o). The acetyl derivative crystallises as elongated prisms from EtOH with m 74o. [Chapman et al. J Chem Soc 3028 1927, Shriner et al. J Am Chem Soc 61 2325 1939, Beilstein 6 H 1154, 6 II 1118, 6 III 6656.]
