Application:

Used as synthesis intermediates. It is an important intermediate for the synthesis of 3, 3 ', 4, 4' diphenyl ether tetracarboxylic dianhydride (abbreviated as monoether anhydride ODPA). ODPA is one of the important monomers for high temperature resistant resins such as polyimide, polyetherimide, polyesterimide, polyamidoimide, polymaleimide, polyaramid, etc. for new special engineering plastics. It can also be used as a crosslinking agent for synthetic polymer materials such as high-performance heat-resistant epoxy resin and polyurethane.

Storage:

Store in a cool and ventilated warehouse, away from fire and heat sources.
