What is 2-HYDROXY-1,3,5-BENZENETRICARBALDEHYDE?
Chemical properties
2-Hydroxy- 1,3,5-benzenetricarbaldehyde has a very limited solubility in most organic solvents and in water. It dissolves well in DMSO and in hot DMF, and the latter can be used as a recrystallization solvent. While the trialdehyde 3 is colorless in its free acid form, its anion absorbs light in the visible region giving the compound a yellow coloration in solutions when dissociation can occur. The yellow sodium salt of 2-hydroxy- 1,3,5-benzenetricarbaldehyde is only slightly soluble in water.
Synthesis
2-Hydroxybenzene-1,3,5-tricarbaldehyde is synthesized from phenol or 4-hydroxybenzaldehyde[1].
