Description

We also offer Phthalic Anhydride.

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.
