Method & chromatogram
Qualitative and quantitative analysis by Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS). Method B: Agilent 1290 Infinity II + 6495 QQQ (ESI+). Column: Agilent Poroshell 120 EC-C18, 2.1×100 mm, 2.7 µm. Solvent A: 0.1% formic acid in H₂O; Solvent B: 0.1% formic acid in acetonitrile. Precursor ion [M+5H]⁵⁺ at 947.90 Da.
Quantifier (MRM) · 947.9 › 136.1 · CE 30 V — Qualifier (MRM) · 947.9 › 110.1 · CE 35 V
LC-MS/MS chromatogram (MRM response vs. retention time in minutes) shows a single dominant retatrutide peak at RT 6.36 min with no significant impurity peaks.
