Description

This bifunctional sulfonated diamine integrates two amino groups flanked by rigid biphenyl and disulfonic acid moieties, enabling robust conjugation in polyimide synthesis. The electron-rich aromatic core enhances thermal stability, while the pendant sulfonic acids promote solubility in polar media.

Application

4,4'-Diamino-[1,1'-biphenyl]-3,3'-disulfonic acid serves as a versatile building block for sulfonated aromatic diamines, enabling the synthesis of polyamides, dyes, and functional materials with enhanced solubility and thermal stability. Its two sulfonic acid groups provide excellent water solubility and facilitate purification via ion-exchange chromatography, while the para-aminobiphenyl core supports robust coupling reactions under standard conditions. The molecule exhibits good bench stability and functions effectively in both solution-phase and solid-phase synthetic workflows.
