Chemical Structure
Description
The molecular framework of (S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)undecanoic acid (C26H33NO4) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)undecanoic acid (CAS 1443546-27-7), molecular formula C26H33NO4 and molecular weight 423.54 g/mol, is a CATO reference standard with documented purity and traceability.
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.
