Usage

General Description

"[1,1'-Biphenyl]-4,4'-diamine sulphate" is a chemical compound often used as an intermediate in industrial chemistry. As a sulfate salt of 4,4'-Biphenyldiamine, it features two phenyl rings linked by a two-atom chain. The biphenyl component, comprised of two benzene rings, contributes to the compound's stability, while the diamine allows for strong bonding potential. This makes it an effective agent in the synthesis of other chemicals. Prolonged exposure can cause eye irritation and skin sensitivity, and environmental precautions must be taken when disposing of this substance due to potential impact on aquatic life.
