1.Feedstock Into Phthalic Anhydride Chemistry: Industry profiles describe phthalic acid as a feedstock for phthalic anhydride production, the intermediate behind plasticizers, dyes, polyester resins and polymer modifiers, which keeps the acid relevant to anhydride and downstream buyers.
2. Organic Reagent For Phthalate Esters: It is used as an organic reagent and building block for synthesising phthalate esters, the plasticisers that soften PVC and appear in coatings, adhesives and other formulated polymer products.
3. Building Block For Alkyd And Polyester Resins: It acts as an acid component in polyesters and alkyd resins and as a building block in specialty resins and crosslinking agents for industrial coatings and inks.
4. Intermediate For Dyes And Pigments: It is used in the production of anthraquinone, phenolphthalein and phthalocyanine pigments and as an intermediate for azo dyes and organic pigments.
