Bis(4-nitrophenyl) carbonate (CAS NO : 5070-13-3)

Bis(4-nitrophenyl) carbonate (CAS No: 5070-13-3) is rapidly evolving as a high-performance alternative to phosgene in the global speciality chemicals market, primarily due to its utility as a safer, solid-state carbonylating agent for the synthesis of complex symmetrical and unsymmetrical ureas and carbamates. This reagent is gaining significant traction within the pharmaceutical CDMO sector, particularly in the production of therapeutic peptides and antibody-drug conjugates (ADCs) where its role in forming activated p-nitrophenyl esters ensures high coupling efficiency and precision in bioconjugation workflows. Furthermore, the compound is seeing expanded industrial adoption in polymer chemistry for the development of high-specification polycarbonate materials and as a cross-linking agent that enhances the thermal stability and mechanical integrity of advanced engineering plastics.
