What is Isophthalic acid CAS 121-91-5？

Isophthalic acid (IPA), also known as 1, 3-phthalic acid or isophthalic acid, has strong heat resistance, hydrolysis resistance and chemical resistance, can occur salt formation, dehydration, hydrogenation, halogenation and other reactions, the largest use is used as an intermediate in the production of unsaturated polyester resin. Secondly,Isophthalic acid (IPA) is used for the manufacture of polyester resin, alkyd resin (the main use of paint manufacturing) and printing ink. In addition, it can also be used to strengthen plastics and packaging, manufacture film color modifier, paint and polyester fiber dyeing modifier and medicine, etc., development and utilization prospects are broad.
