Description

Structurally, (2S,3R)-3-(((S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(tert-butoxy)propanoyl)oxy)-2-((tert-butoxycarbonyl)amino)butanoic acid (C31H40N2O9) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 584.66 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO supplies (2S,3R)-3-(((S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(tert-butoxy)propanoyl)oxy)-2-((tert-butoxycarbonyl)amino)butanoic acid (CAS 944283-28-7), a certified reference material (molecular formula C31H40N2O9, MW 584.66 g/mol) for analytical method development and quality control.

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.
