Application

2-Nitrobenzyl alcohol serves as a key photolabile protecting group for carboxylic acids, amines, and alcohols in organic synthesis. It is widely employed in the development of light-sensitive compounds and caged molecules for controlled release studies. Researchers also utilize it as a precursor for synthesizing nitrobenzyl-based linkers in solid-phase peptide synthesis (SPPS).
