| 3,4,5-Trimethoxyphenol Usage And Synthesis |
| 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.
