6-NITROVERATRYL CHLOROFORMATE Chemical Properties,Usage,Production

Uses

4,5-Dimethoxy-2-nitrobenzyl chloroformate is used as a reagent for protection of amines, for use in N-protection of bases in nucleotide synthesis, photochemical protecting groups in organic synthesis. It is used as pharmaceutical intermediate.

Uses

4,5-Dimethoxy-2-nitrobenzyl chloroformate (NVOC-Cl) is a photolabile protecting reagent, commonly used in peptide or nucleotide synthesis to protect amines and hydroxyl groups. General applications are:

• Preparation of inactive, caged protein conjugates which can be activated by irradiating near-ultraviolet light.
• Solid-phase synthesis of base-sensitive S-acylthioethyl (SATE)-prooligonucleotides.
• Modification of surface properties by introducing photocleavable NVOC moiety into chitosan to control cell attachment.
