CAS 121-91-5 High Purity Factory Supply Isophthalic Acid/Ipa in Stock C8h6o4 Powder Industrial Grade

sophthalic acid (IPA for short), also known as 1,3-phthalic acid or isophthalic acid, has strong heat resistance, hydrolysis resistance and chemical resistance, and can undergo salt formation, dehydration, hydrogenation, halogenation, etc. Reaction, the biggest use is as an intermediate Chemicalbook body for the production of unsaturated polyester resins, followed by the production of polyester resins, alkyd resins (mainly used for paint manufacturing) and printing inks. In addition, it can also be used to reinforce plastics and packaging, to produce film film couplers, paints and polyester fiber dyeing modifiers, and medicines. It has a broad development and utilization prospects.  It used in the production of alkyd resins, unsaturated polyester resins and other high polymers and plasticizers, also used in the production of film film couplers, coatings and polyester fiber dyeing modifiers and medicines. And Used as a chromatographic analysis reagent and also used in organic synthesis.
