CATO supplies (S)-2-((S)-1-(((9H-fluoren-9-yl)methoxy)carbonyl)-6-oxo-1,7-diazaspiro[4.4]Nonan-7-yl)-4-methylpentanoic acid (CAS 129605-53-4), a certified reference material (molecular formula C28H32N2O5, MW 476.56 g/mol) for analytical method development and quality control.
The molecular framework of (S)-2-((S)-1-(((9H-fluoren-9-yl)methoxy)carbonyl)-6-oxo-1,7-diazaspiro[4.4]Nonan-7-yl)-4-methylpentanoic acid (C28H32N2O5) is characterized by a steroid 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).
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.
