Product Description

Isophthalic acid
CAS NO. 121-91-5
MW:C8H6O4
MF:166.13
1.Performance and use:
Isophthalic acid (IPA), also known as 1,3-phthalic acid or isophthalic acid, has strong heat resistance, hydrolysis resistance, and chemical resistance. It can undergo reactions such as salt formation, dehydration, hydrogenation, and halogenation. Its main use is as an intermediate in the production of unsaturated polyester resins, followed by the manufacture of polyester resins, alkyd resins (mainly used in coating manufacturing), and printing inks
Used for the production of alkyd resins, unsaturated polyester resins, and other high polymers and plasticizers, as well as for the manufacture of film color couplers
