One of the principal uses of Dimethyl Isophthalate is as an intermediate in the synthesis of polyesters. In order to obtain the structural strength needed in fibers and films, the polyester must be of high molecular weight. The most efficient route to these high molecular weights is through transesterification of methyl ester with a glycol. A specially purified methyl ester is needed in this application.

It is used primarily to improve the clarity and strength of PET carbonated drink bottles.
Another significant applicant area is in optical resin, Thermoplastic elastomer, engineering plastics.
