1,3-Dihydroxynaphthalene
1,3-Dihydroxynaphthalene (CAS: 132-86-5), also called naphthoresorcinol, is a white to off-white crystalline dihydroxy naphthalene with two phenolic groups positioned on the same ring. The diol is readily oxidised and coupled, so it is a valuable intermediate for dyes, pigments, photographic chemicals and antioxidants, and it works as a chromogenic reagent that gives coloured products with sugars, uronic acids and certain metal ions. It is also used in analytical determinations and as a building block for specialty organic synthesis. The powder is light- and air-sensitive and should be stored sealed, cool and protected from light.
• Dye and pigment intermediates: a coupling component for azo dyes, mordant dyes and pigment synthesis.
• Analytical reagent: naphthoresorcinol is used for the colorimetric detection of carbohydrates, uronic acids and aldehydes.
• Antioxidant and stabiliser chemistry: applied in the preparation of antioxidant and stabiliser products.
• Organic synthesis: a difunctional phenol building block for pharmaceutical, agrochemical and specialty intermediates.
