O-nitrobenzyl

Definition

o-nitrobenzyl refers to a chemical structure that features a benzene ring with a nitro group (-NO2) attached to the ortho position relative to another functional group. This particular arrangement makes o-nitrobenzyl derivatives important in the development of photoactivatable compounds and caged drugs, which can release biologically active agents upon exposure to light. The ability to control the release of these agents makes them valuable tools in various fields, including biochemistry and pharmacology.
