Citalopram-Oxalat S-Isomer, auch Escitalopram-oxalat genannt, CAS 219861-08-2, ist das optisch aktive S-Enantiomer des selektiven Serotonin-Wiederaufnahmehemmers Citalopram. Als Monooxalat-Salz von (1S)-1-(3-(Dimethylamino)propyl)-1-(4-fluorophenyl)-1,3-dihydroisobenzofuran-5-carbonitril besitzt es die Summenformel C22H23FN2O5 und eine Molmasse von 414,43 g/mol. Im Verunreinigungsprofil ist es als enantiomerer Verwandter oder prozessbedingte Spezies relevant, die aus unvollständiger chiraler Auftrennung oder stereochemischer Inversion bei der Synthese entstehen kann. Die Bestimmung erfolgt typischerweise mittels chiraler LC und LC-MS/MS, ergänzt durch NMR oder HRMS zur regulatorischen Absicherung.
