CAS: 7693-46-1 | C7H4ClNO4 | 201.562 g/mol

4-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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
