Dimethyl 5-hydroxyisophthalate, 1 X 50 g (371785-50G)

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. Novel building block derived from dimethyl 5-hydroxyisophthalate was used to prepare sterically crowded polyether dendrons, via O-allylation/Claisen rearrangement reactions. Dimethyl 5-hydroxyisophthalate may be used in the preparation of: •bis(phebox) derivative of the cyclophosphazene •5-{2-[2-(2-methoxyethoxy)ethoxy]ethoxy}benzene-1,3-dicarboxylic acid dimethyl ester •fullerene derivative bearing a triethylene glycol-type polar head group
