Uses
Dimethyl 5-Hydroxyisophthalate is a useful synthetic intermediate in the synthesis of N,N?-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 Description
Dimethyl 5-hydroxyisophthalate undergoes a base-catalyzed nucleophilic oxirane ring-opening addition reaction with allyl glycidyl ether, to afford 5-substituted derivatives of isophthalic acid. Influence of third component, i.e. a series of 1,ω-alkanediols on the copolymerization reaction of dimethyl 5-hydroxyisophthalate with poly(ethylene glycol) has been studied. Lipase-catalyzed condensation polymerization of dimethyl 5-hydroxyisophthalate with polyethylene glycol is reported.
