Applications · 3 items

Uses4-Nitrophenyl chloroformate can be used:As a reagent for the activation of amines, alcohols and thiols.In the synthesis of 4-substituted phenyl derivatives of 1,2,4-triazolidindiones (urazoles).In the solid-phase synthesis of 3-aryl-2,4-quinazolinedione derivatives with potent anti-cancer property.In the preparation of poly(oxyethylene) modified dextrans.To synthesize a cleavable, heterobifunctional cross-linker for reversible conjugation of amines to thiol-modified DNA.

Uses4-Nitrophenyl chloroformate is used in the synthesis of poly(oxyethylene) modified dextrans. It is also used to prepare a cleavable, heterobifunctional cross-linker for reversible conjugation of amines to thiol-modified DNA. Further, it is used in the synthesis of mixed, activated carbonates, thiocarbonates and activated urethanes. In addition to this, it is used in the preparation of 4-nitrophenyl diazoacetate with diazomethane. It is an ester of chloroformic acid used in the immobilization of enzymes and other biomolecules.

Description4-Nitrophenyl chloroformate, also known as p-nitrophenyl chloroformate, is a coupling agent used in the synthesis of ureas, carbamates, and carbonates. It is also used as a building block in solid-phase peptide synthesis (SPPS) to obtain altered side chain functionalities in peptides.
