概况
Butyne-DOTA-tris(t-butyl ester) (also known as tert-butyl 2-[4-[2-(but-3-ynylamino)-2-oxoethyl]-7,10-bis[2-[(2-methylpropan-2-yl)oxy]-2-oxoethyl]-1,4,7,10-tetrazacyclododec-1-yl]acetate) (CAS 2125661-54-1, MF C32H57N5O7, MW 623.82) 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.
