The o-nitrobenzyl group (o-NB) is utilized frequently in polymer and materials science. It covers the use of based cross-linkers for photodegradable hydrogels, o-NB side chain functionalization in (block) copolymers, o-NB side chain functionalization for thin film patterning, o-NB for self-assembled monolayers, photo cleavable block copolymers, and photo cleavable bioconjugates.
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.
