Descrizione

Applicazioni

• Improved, one-pot synthesis of 6-[(18) F]fluorodopamine and quality control testing for use in patients with neuroblastoma.: This study presents an improved method for synthesizing 6-[(18) F]fluorodopamine using Kryptofix 222. The one-pot synthesis process enhances efficiency and quality control, making it suitable for clinical applications in neuroblastoma patients (Vāvere et al., 2018).
• Efficient radiosynthesis and non-clinical safety tests of the TSPO radioprobe [(18)F]FEDAC: Prerequisites for clinical application.: Kryptofix 222 is utilized in the radiosynthesis of [(18)F]FEDAC, a radioprobe for TSPO imaging. The study highlights the efficiency and safety of the synthesis process, facilitated by Kryptofix 222, and its potential for clinical application (Kawamura et al., 2016).
• Fully automated one-pot radiosynthesis of O-(2-[18F]fluoroethyl)-L-tyrosine on the TracerLab FX(FN) module.: This research demonstrates the automated synthesis of O-(2-[18F]fluoroethyl)-L-tyrosine, employing Kryptofix 222 as a phase transfer catalyst. The automated process significantly improves the synthesis efficiency (Bourdier et al., 2011).
• Electrochemical concentration of no-carrier-added [(18)F]fluoride from [(18)O]water in a disposable microfluidic cell for radiosynthesis of (18)F-labeled radiopharmaceuticals.: Kryptofix 222 plays a crucial role in the electrochemical concentration of [(18)F]fluoride, facilitating the radiosynthesis of various (18)F-labeled radiopharmaceuticals in a microfluidic cell, enhancing the overall efficiency and yield (Saiki et al., 2010).
