Description

Resorcinol CAS NO 108-46-3 is a white to off-white crystalline dihydroxybenzene compound, a versatile meta-isomer of benzenediol. It serves as a critical building block and intermediate in the synthesis of pharmaceuticals, dyes, and high-performance adhesives. This chemical is essential for manufacturers in the rubber, wood bonding, personal care, and specialty chemical industries seeking reliable and high-purity raw materials.

Application

• Rubber Industry: A key component in the production of resorcinol-formaldehyde-latex (RFL) systems for bonding textile cords to rubber in tires, hoses, and conveyor belts.
• Wood Adhesives: Used in the formulation of high-performance, waterproof phenolic and resorcinol-formaldehyde resins for marine-grade plywood and laminated beams.
• Pharmaceutical Synthesis: An important intermediate in the manufacture of various active pharmaceutical ingredients (APIs), including certain antiseptics and UV absorbers.
• Hair Dyes & Cosmetics: Functions as a coupling agent in oxidative hair colorants and is used in some acne treatment and skincare formulations.
• Dye & Pigment Production: Serves as a precursor for azo dyes, fluorescent dyes, and other specialty colorants.
• UV Stabilizers & Antioxidants: Used in the synthesis of compounds that protect polymers and coatings from degradation caused by sunlight and oxidation.
• Flame Retardants: Incorporated into the synthesis of certain flame-retardant materials for textiles and plastics.
• Agricultural Chemicals: Acts as an intermediate in the production of some herbicides and fungicides.

Quality Control

Our Resorcinol is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and physical properties. Certificates of Analysis (COA) documenting compliance with relevant standards, including USP, BP, or technical grades, are provided to guarantee supply reliability and batch-to-batch consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its properties of being easily oxidized (store under inert atmosphere) and light-sensitive, it is recommended to store under an inert atmosphere such as nitrogen for long-term storage to maintain optimal purity and shelf life.
