Automatic synthesis of 4-[18F]fluorobenzaldehyde has been developed by a commercially available TRACERlab(TM) FXF-N synthesis module to be used as prosthetic group for amino-oxy functionalized peptide labelling in clinical routine application. In addition a handmade purification device (HPD) has been setup to perform automatic cartridge purification as well as to back-up the reactor where one-pot synthesis is not applicable. Cartridges for solid phase extraction such as C18, C8, phenyl has been tested to best perform purification as well as activity recovery. Radiochemical yield (RCY) at end of synthesis (EOS) was in average 67% after about 45 min (90% decay corrected at EOB). The RCY of the entire procedure was 54% with a radiochemical purity above 99%.

Abstract
Automatic synthesis of 4-[18F]fluorobenzaldehyde has been developed by a commercially available TRACERlab(TM) FXF-N synthesis module to be used as prosthetic group for amino-oxy functionalized peptide labelling in clinical routine application. In addition a handmade purification device (HPD) has been setup to perform automatic cartridge purification as well as to back-up the reactor where one-pot synthesis is not applicable. Cartridges for solid phase extraction such as C18, C8, phenyl has been tested to best perform purification as well as activity recovery. Radiochemical yield (RCY) at end of synthesis (EOS) was in average 67% after about 45 min (90% decay corrected at EOB). The RCY of the entire procedure was 54% with a radiochemical purity above 99%.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
