Application


  • Identification of Iminium Intermediates Generation in the Metabolism of Tepotinib Using LC-MS/MS: In Silico and Practical Approaches to Bioactivation Pathway Elucidation.: The research identifies iminium intermediates in the metabolism of tepotinib using liquid chromatography-mass spectrometry. Potassium cyanide is utilized to trap reactive intermediates, providing insights into drug metabolism pathways (Abdelhameed et al., 2020).

  • Synthesis of stable-isotope-labeled N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide and N-(3-dimethylaminopropyl)-N′-ethylurea.: This paper describes the synthesis of stable-isotope-labeled compounds using potassium cyanide in the synthesis process to understand the chemical structure and reactivity of these labeled compounds (Cao et al., 2020).

  • Carbon-13 synthesis and NMR spectroscopic geometric isomer evaluation to support the filing of teriflunomide.: The study involves the synthesis of carbon-13 labeled teriflunomide and its isomers, using potassium cyanide in the synthetic pathway. The NMR spectroscopic analysis helped in the evaluation of geometric isomers (Kurz et al., 2021).

  • A hybrid lipid membrane coating "shape-locks" silver nanoparticles to prevent surface oxidation and silver ion dissolution.: This research develops a hybrid lipid membrane to stabilize silver nanoparticles, using potassium cyanide in the analytical phase to measure the prevention of silver ion dissolution and oxidation (Miesen et al., 2020).
