4,5-二甲氧基-2-硝基溴苄

4,5-Dimethoxy-2-nitrobenzyl bromide (DMNBB, 1-(Bromomethyl)-4,5-dimethoxy-2-nitrobenzene) is a 4,5-dimethoxy-2-nitrobenzyl derivative. 4,5-Dimethoxy-2-nitrobenzyl (DMNB) group of DMNBB is used as a photolabile protecting group in caging technology to develop pro-drugs. Synthesis of 1-(bromomethyl)-4,5-dimethoxy-2-nitrobenzene by using 6-nitroveratraldehyde as starting reagent has been reported.

4,5-Dimethoxy-2-nitrobenzyl bromide (DMNB bromide, 6-nitroveratryl bromide) is suitable reagent used in the synthesis of N-(4,5-dimethoxy-2-nitrobenzyl)vanillylamine which forms caged vanilloid. It may be used in the synthesis of the following:

• 4-(4′,5′-dimethoxy-2-nitrobenzyloxy)benzaldehyde, a DMNB-caged aldehyde
• N-[4-[(4,5-dimethoxy-2-nitrobenzyl)oxy]-3-methoxybenzyl]acetamide
• caged derivative of pyridostatin ([C]-PDS)
• photosensitive polyimide (PI-DMNB)
• caged β-ecdysone
• 4-tert-butyldimethylsilyloxy-1-(2-deoxy-3,5-di-O-toluoyl-β-D-ribofuranosyl)-2-(6-nitroveratrylthio)-1H-benzimidazole, an intermediate in synthesis of phosphoramidite bearing 4-hydroxy-2-mercaptobenzimidazole (SB^NV) nucleobase
• alkylation of dihydrofluorescein
• 4-(4′,5′-Dimethoxy-2′-nitrobenzyloxy)benzaldehyde
