Benzene-1,3-diol

Benzene-1,3-diol is an organic chemical compound with the molecular formula C6H6O2 and CAS number 108-46-3. Also known as resorcinol, it consists of a benzene ring with two hydroxyl groups positioned at the 1 and 3 positions. With a molecular weight of 110.11 g/mol, this dihydroxybenzene derivative appears as white crystals or powder and is highly soluble in water and alcohol.

Benzene-1,3-diol appears as white to light yellow crystalline powder or needles at room temperature. It has a melting point of approximately 110°C and is highly soluble in water, ethanol, and ether. The compound exhibits moderate volatility and has a characteristic phenolic odor. It readily undergoes oxidation and can form colored complexes with metal ions, making it useful in various analytical applications.

Benzene-1,3-diol is primarily used in the production of adhesives, particularly resorcinol-formaldehyde resins for wood bonding applications. It serves as an intermediate in pharmaceutical synthesis, rubber production, and dye manufacturing. The compound is also utilized in cosmetic formulations, hair dyes, antiseptic preparations, and as a chemical intermediate for various organic syntheses in the pharmaceutical and chemical industries.

Benzene-1,3-diol requires careful handling due to its classification as Acute Tox. 4, Skin Irrit. 2, and Skin Sens. 1B. Wear appropriate PPE including nitrile gloves, safety goggles, and protective clothing. Work in well-ventilated areas or under fume hoods to avoid inhalation. Avoid skin and eye contact, and prevent dust formation. Use non-sparking tools and ensure proper grounding to prevent static electricity buildup.

Benzene-1,3-diol should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep containers away from incompatible materials such as strong oxidizing agents and strong bases. Store at temperatures below 25°C and protect from moisture to prevent degradation. Ensure storage areas are equipped with appropriate spill containment measures and emergency equipment.

Benzene-1,3-diol contact requires immediate action due to its skin and eye irritation properties. For skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. In case of eye contact, flush immediately with clean water for 15 minutes and remove contact lenses if present. If inhaled, move to fresh air. Seek medical attention if symptoms persist or develop.

Benzene-1,3-diol disposal must comply with local and national hazardous waste regulations due to its classification as harmful to aquatic life. Contact licensed waste disposal companies for proper treatment and disposal. Small quantities can be treated through controlled incineration at authorized facilities. Never dispose of in regular waste streams, sewers, or waterways. Keep detailed disposal records as required by environmental regulations.

Benzene-1,3-diol is classified under ADR as Class 6.1 (toxic substances), Packing Group III for transportation purposes. It requires appropriate UN specification packaging with proper labeling including GHS07, GHS08, and GHS09 pictograms. Transport vehicles must carry appropriate documentation, emergency procedures, and safety equipment. Drivers require ADR training certification, and shipments must comply with quantity limitations and routing restrictions for dangerous goods.

Benzene-1,3-diol is regulated under REACH regulation in Europe and must comply with CLP classification requirements. While not currently listed as a SVHC (Substance of Very High Concern), it is subject to standard chemical safety reporting and supply chain communication requirements. Users must maintain safety data sheets, implement appropriate risk management measures, and ensure proper hazard communication throughout the supply chain according to CLP regulations.
