Products Description of Phenol CAS#108-95-2
Phenol, with the chemical formula C₆H₅OH (C₆H₆O), is a white crystalline compound characterized by its excellent versatility and chemical reactivity, which are attributed to the hydroxyl group attached to the benzene ring.
It is widely used as an important intermediate in the synthesis of pharmaceuticals, including aspirin, and plays a significant role in the production of resins, plastics, and synthetic fibers such as nylon. Historically, phenol has been used as a disinfectant due to its ability to denature proteins and disrupt cell membranes.
In addition, phenol is applied in the detergent industry and analytical chemistry. Due to its high reactivity and potential toxicity, proper handling procedures and safety precautions are required. Phenol is biodegradable but should be managed with appropriate waste treatment methods to minimize environmental impact. Its unique chemical properties and extensive applications make it a vital material in various industrial processes.
