Chemical Structure

(2-pyridyldithio)-PEG1-hydrazine CAS 111625-28-6 chemical structure

Description

(2-pyridyldithio)-PEG1-hydrazine (C7H9NOS2) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
