WebIn our previous work, the experimental log D of strongly ionized compounds could be determined well by ion-pair reversed-phase liquid chromatography (IP-RPLC) on an octadecyl-poly (vinyl alcohol) column using the log D -log kw-IP model established by different types of model compounds. WebIn partnership with Enamine Ltd. we built the world's largest collection of commercially available compounds, featuring 36,043,260,372 virtual products. Using our CoLibri technology, we coded the Enamine synthesis protocols and in-stock starting materials as a searchable Chemical Space.
Web16 okt. 2024 · Ionizable compounds are typically water miscible and are best separated/purified using reversed-phase methods. The challenge with these water-soluble compounds is getting them to retain on hydrophobic (i.e. C18) media and elute in a tight band, the goal if you seek to purify them.
Ionization (or ionisation) is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes.
