The molecular framework of (5S,8S,9R)-8-Benzoyl-2-((1S)-1,4-dihydroxyhex-2-en-1-yl)-9-hydroxy-8-methoxy-3-methyl-1-oxa-7-azaspiro[4.4]non-2-ene-4,6-dione (C22H25NO8) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(5S,8S,9R)-8-Benzoyl-2-((1S)-1,4-dihydroxyhex-2-en-1-yl)-9-hydroxy-8-methoxy-3-methyl-1-oxa-7-azaspiro[4.4]non-2-ene-4,6-dione (CAS 77409-68-8) is a high-purity analytical reference standard with the molecular formula C22H25NO8 and a molecular weight of 431.44 g/mol.
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.
