概况
DOTAGA-anhydride (also known as 2-[4,10-bis(carboxymethyl)-7-(2,6-dioxooxan-3-yl)-1,4,7,10-tetrazacyclododec-1-yl]acetic acid) (CAS 1375475-53-8, MF C19H30N4O9, MW 458.46) is a DOTA-family macrocyclic chelator building block used in radiopharmaceutical and metal-conjugate research. Programs working with this compound typically focus on selective functionalisation, radiometal compatibility (e.g., ⁹⁰Y, ¹⁷⁷Lu, ⁶⁴Cu), and conjugate stability. Custom synthesis, process scale-up and supply planning are available through CHEMOS R&D and manufacturing facilities.
