2-phenylphenol

2-phenylphenol is an organic compound with the molecular formula C12H10O and CAS number 90-43-7. This biphenyl derivative consists of two benzene rings connected with a hydroxyl group (-OH) attached to one ring. With a molecular weight of 170.21 g/mol, it belongs to the phenol family of compounds and exhibits both aromatic and phenolic chemical properties, making it useful in various industrial applications.

2-phenylphenol appears as white to light yellow crystalline flakes or powder at room temperature. It has a characteristic mild phenolic odor and melts at approximately 56-58°C. The compound is poorly soluble in water but readily dissolves in organic solvents such as ethanol, acetone, and benzene. It exhibits stability under normal conditions but can decompose when exposed to strong oxidizing agents or extreme temperatures.

2-phenylphenol serves primarily as a fungicide and bactericide in agricultural applications and post-harvest treatment of citrus fruits. It is widely used as a preservative in cosmetics, personal care products, and household cleaners due to its antimicrobial properties. Additionally, it functions as an intermediate in the synthesis of other chemicals and finds applications in the production of resins, plasticizers, and rubber chemicals in industrial processes.

2-phenylphenol requires careful handling due to its corrosive and sensitizing properties. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, and protective clothing to prevent skin and eye contact. Work in well-ventilated areas or use local exhaust ventilation to minimize inhalation exposure. Avoid generating dust and never eat, drink, or smoke when handling this substance. Wash hands thoroughly after use and before breaks.

2-phenylphenol should be stored in tightly closed original containers in a cool, dry, and well-ventilated area away from direct sunlight and heat sources. Keep away from incompatible materials such as strong oxidizing agents, acids, and bases. Storage temperature should remain below 25°C to maintain stability. Ensure proper labeling and restrict access to authorized personnel only. Regular inspection of containers for damage or leakage is recommended.

Skin contact with 2-phenylphenol requires immediate removal of contaminated clothing and thorough washing with soap and water for at least 15 minutes. In case of eye contact, flush immediately with clean water for at least 15 minutes while holding eyelids open. If inhaled, move the person to fresh air and keep them at rest. For ingestion, do not induce vomiting and rinse mouth with water. Seek immediate medical attention in all cases.

2-phenylphenol disposal must comply with local and national hazardous waste regulations due to its classification as dangerous for the aquatic environment. The substance should be collected in suitable containers and handed over to licensed waste disposal companies for incineration at high temperatures. Never discharge into sewers, waterways, or soil. Small quantities can be absorbed with inert material and disposed of as hazardous waste following proper documentation procedures.

2-phenylphenol is classified as ADR Class 9 (Miscellaneous dangerous substances), Packing Group III for transportation. It must be packaged in UN-approved containers with proper labeling including the UN number and hazard markings. Transport vehicles should carry appropriate documentation including transport documents and emergency instructions. Drivers must hold valid ADR certification, and the substance should be segregated from incompatible materials during transport.

2-phenylphenol is regulated under various European legislation including REACH and CLP regulations due to its hazardous classification. It requires safety data sheets and proper classification as Carcinogenic Category 2, Skin Corrosive Category 1, and hazardous to aquatic environment. The substance is subject to biocide regulations when used as a preservative and may require specific authorizations depending on the intended use and concentration levels in different applications.
