What is Dimethyl terephthalate CAS 120-61-6?

Dimethyl terephthalate CAS 120-61-6 is a white crystalline solid at room temperature and pressure, which contains two ester groups. These ester groups are highly electrophilic and are easily attacked by nucleophiles. Therefore, dimethyl phthalate can participate in a variety of nucleophilic reactions, such as acid-catalyzed ester hydrolysis, nucleophilic substitution reactions, etc. Dimethyl phthalate can undergo transesterification and polycondensation reactions, hydrogenation and hydrogenolysis reactions and hydrolysis reactions.
