Introduction of 118-48-9 :

Isatoic anhydride is a single-adduct forming reagent and a monofunctional SHAPE reagent. Isatoic anhydride reacts with the 2'-hydroxyl group of RNA nucleotides via a single reactive group to form a single adduct, without forming cross-links between nucleotides. In SHAPE-JuMP experiments, Isatoic anhydride serves as a control reagent for single-adduct formation, which is used to distinguish true cross-links from single-adduct formation[1]. In Vitro:Isatoic anhydride (incubated for 15-30 min) forms monoadducts exclusively with the catalytic domain RNA of RNase P and VS ribozyme RNA[1].
