Resorcinol is a white crystalline, water-soluble organic compound known as 1, 3-dihydroxybenzene (C₆H₆O₂) used mainly in the production of resins and plastics, as a key ingredient in adhesives like resorcinol glue, and in some pharmaceutical products for its antiseptic properties. It is recognized as a phenol derivative that can turn pink in air and light and is hygroscopic. Uses Adhesives: A primary component in resorcinol glues for strong, waterproof wood applications, such as plywood. Resins and Polymers: Utilized in the production of various resins and other polymers. Pharmaceuticals: Acts as a disinfectant or antiseptic in some topical products for skin conditions like acne, eczema, and warts. Skin Sensitivity: Resorcinol can act as a sensitizer and is often used to treat various skin conditions. Industrial Resin production: It is used with formaldehyde to produce strong adhesives for tires, wood products, and other rubber-bonded items. Dyes: Resorcinol is a key intermediate in the production of diazo dyes and fluorescent dyes like fluorescein. Chemical intermediate: It is used to produce a variety of pharmaceuticals, explosives, and other organic chemical compounds. Other applications: It is also used in photographic developers, UV absorbers, and cosmetics.
