Product Technical Details

Product Overview

Bis(4-nitrophenyl) Carbonate, frequently identified by its CAS registry number 5070-13-3, stands as a pivotal reagent in modern organic synthesis and pharmaceutical manufacturing. This specialized carbonate ester serves primarily as a highly effective condensation agent, facilitating the formation of carbamate linkages and activating hydroxyl groups for subsequent nucleophilic attacks. Our facility produces this compound under stringent quality control protocols to ensure consistent performance in sensitive chemical transformations.

As a derivative of carbonic acid, this molecule features two nitrophenyl groups that act as excellent leaving groups due to the electron-withdrawing nature of the nitro substituents. This chemical structure makes it superior for reactions requiring mild conditions while maintaining high reaction rates. It is particularly valued in the synthesis of complex pharmaceutical intermediates where precision and purity are paramount. The compound is stable under standard storage conditions but requires anhydrous environments during reactive processes to prevent hydrolysis.
