Resorcinol is an important multifunctional chemical raw material and is widely used in various industries such as pharmaceuticals, cosmetics, rubber, resins, and dyes due to its high chemical reactivity.

1. Pharmaceutical and Personal Care

• Antibacterial and disinfectant products: Resorcinol has bactericidal and antifungal properties and can be used in disinfectants, mouthwashes, and preservative ointments.

• Dermatological medications: Used for treating acne, eczema, and skin pigmentation; it is an ingredient in some depigmenting or anti-skin disease ointments.

• Hair dyes: A key ingredient in permanent hair dyes, helping dye molecules bind to hair proteins during oxidative dyeing.

2. Rubber and Resin Industry

• Rubber antioxidant: Acts as an antioxidant and crosslinking promoter in rubber processing, improving heat resistance and aging resistance.

• Resin production: Used to synthesize phenolic resins, epoxy resins, and specialty resins, enhancing high-temperature resistance and chemical corrosion resistance.

3. Pesticides and Chemical Intermediates

• Pesticide intermediates: Used in the synthesis of fungicides and insecticides, such as certain phenolic fungicides.

• Dye and pigment intermediates: Employed in the production of azo dyes, indigo, and other high-value dyes.

• Pharmaceutical intermediates: Used in the synthesis of antibiotics, analgesics, and other chemical intermediates.

4. Optical and Electronic Materials

• Photosensitive materials: Used in the production of photosensitive development materials.

• Electronic chemicals: Sometimes used as electrode modification agents in electronic chemistry or conductive materials.
