Overview
NO2A-Butyne-bis(t-Butyl ester) (also known as tert-butyl 2-[4-[2-(but-3-ynylamino)-2-oxoethyl]-7-[2-[(2-methylpropan-2-yl)oxy]-2-oxoethyl]-1,4,7-triazonan-1-yl]acetate) (CAS 2125661-91-6, MF C24H42N4O5, MW 466.62) belongs to the NOTA / NODAGA macrocyclic chelator family used in radiopharmaceutical research. Typical chemistry questions involve protection-group strategy, mono-functionalisation, and conjugation chemistry for peptide or antibody coupling. Project scale-up and custom synthesis are coordinated by the CHEMOS R&D team across laboratory and production sites.
