Product Details

Products Description of Phenol CAS#108-95-2
Phenol, with the chemical formula $𝐶_{6} 𝐻_{5} 𝑂 𝐻$ C6H6O, is a white crystalline substance known for its versatility and reactivity due to the hydroxyl group attached to the benzene ring. It serves as a key precursor in the synthesis of pharmaceuticals, including aspirin, and is integral to the production of resins, plastics, and synthetic fibers like nylon. Phenol's historical use as a disinfectant highlights its ability to denature proteins and disrupt cell membranes. It also plays a role in the detergent industry and analytical chemistry. However, its reactivity and potential toxicity necessitate careful handling with appropriate safety measures. Phenol is biodegradable but requires proper waste management to prevent environmental harm. Its diverse applications and chemical properties make phenol an essential component in a wide range of industrial processes.
