5-Hydroxyisophthalic acid Usage And Synthesis
Chemical Propertieswhite to slightly yellow powder
Uses5-Hydroxyisophthalic Acid is used as a reagent in the synthesis of silver carboxylate metal organic framework (MOF) complexes. 5-Hydroxyisophthalic Acid is also used as the starting material in the synthesis of N,NтАЩ-Bis(2,3-dihydroxypropyl)-5-[(N-(2-hydroxyethyl)carbamoyl)methoxy]-2,4,6-triiodoisophthalamide (B426310); a compound related to Ioversol( I737000) which is a nonionic, low osmolality, radiographic contrast agent.
General DescriptionThe hydrothermal reaction of 5-hydroxyisophthalic acid, Co(II)/Cu(II) and dipyridophenazine, that forms two 3D chiral coordination polymers, was studied.
Synthesis
Dimethyl 5-hydroxyisophthalate

5-Hydroxyisophthalic acid

618-83-7

The general procedure for the synthesis of 5-hydroxyisophthalic acid from dimethyl 5-hydroxyisophthalate was as follows: dimethyl 5-hydroxyisophthalate (40 g, 19.03 mmol) was dissolved in THF (10 mL), followed by the addition of aqueous lithium hydroxide (20 mL, 2 M). The reaction mixture was stirred at 40 °C overnight. Upon completion of the reaction, THF was removed by distillation under reduced pressure. the pH of the remaining aqueous solution was adjusted to about 2 with 6N hydrochloric acid to precipitate the product. The precipitated 5-hydroxyisophthalic acid was collected by filtration and dried in a vacuum oven to give 20 g of white solid product in 58% yield.
