Phthalic acid is an aromatic dicarboxylic acid, with formula C6H4(CO2H)2. It is an isomer of isophthalic acid and terephthalic acid. Any of three isomeric acids having the formula C 8 H 6 O 4 , especially the ortho isomer (orthophthalic acid), a colorless, crystalline, slightly water-soluble solid used chiefly in the manufacture of dyes, medicine, and perfume. Phthalic acid is a colorless, crystalline, slightly water-soluble solid, C 8 H 6 O 2 , the meta isomer of phthalic acid: used chiefly in the manufacture of resins, plasticizers and textile fibers. We also offer specific size crystals.
