Chemical Structure
Description
CATO supplies 4-(3-((((9h-Fluoren-9-yl)methoxy)carbonyl)amino)phenyl)butanoic acid (CAS 867382-45-4), a certified reference material (molecular formula C25H23NO4, MW 401.45 g/mol) for analytical method development and quality control.
Structurally, 4-(3-((((9h-Fluoren-9-yl)methoxy)carbonyl)amino)phenyl)butanoic acid (C25H23NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 401.45 g/mol, it falls into the moderately-high-molecular-weight range. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
