Product Description
Diphenyl Ether (CAS#101-84-8) is a colorless crystalline solid or liquid with a mild and pleasant odor. It melts at approximately 81 °F (27.2 °C), becoming a clear, colorless liquid when heated above its melting point. The compound is recognized for its distinctive floral-green, metallic geranium-like fragrance and is insoluble in water.
Due to its excellent thermal stability and low vapor pressure, Diphenyl Ether is widely used as a heat transfer medium. It is also extensively utilized in the fragrance industry, especially in soap formulations, where it helps carry and release aromas effectively. In addition, Diphenyl Ether serves as an important chemical intermediate in reactions such as halogenation, acylation, and alkylation, contributing to the synthesis of a wide range of organic compounds and materials.
