AZD4694 Precursor (AZ13040214) is the precursor of [ 18 F] AZD4694 for the synthesis of [ 18 F] AZD4694, an amyloid-β imaging ligand with high affinity for amyloid-β plaques. In Vitro AZD4694 Precursor is an amyloid-β imaging ligand with high affinity for amyloid-β plaques. AZD4694 Precursor is a high affinity ( K d = 2.3 nM) radioligand for imaging amyloid-β plaques that displays lower white matter binding compared to other fluorinated amyloid-PET tracers, enabling easier visual reads. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid
