Dimethyl 5-(hydroxymethyl)isophthalate（Cat No.:L025028）is an aromatic ester compound derived from isophthalic acid, featuring two methyl ester groups and a hydroxymethyl substituent at the 5-position of the benzene ring. This multifunctional structure provides both ester and alcohol functionalities, making it a versatile intermediate in organic synthesis and polymer chemistry. It is often used in the preparation of specialty polyesters, plasticizers, and crosslinkable materials. The hydroxymethyl group offers a reactive handle for further modification, such as etherification or esterification, enabling its incorporation into advanced materials, coatings, and functional monomers for industrial and research applications.
