The molecular framework of 1844849-10-0 S4L4MM20B6 PF-06821497 UNII-S4L4MM20B6 1(2H)-Isoquinolinone, 5,8-dichloro-2-((1,2-dihydro-4-methoxy-6-methyl-2-oxo-3-pyridinyl)methyl)-3,4-dihydro-7-((R)-methoxy-3-oxetanylmethyl)- (C22H24Cl2N2O5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
