(2S,3S)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-(3,5-dimethoxyphenyl)-2-hydroxypropanoic acid CAS 959581-18-1 chemical structure

Description

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.

(2S,3S)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-(3,5-dimethoxyphenyl)-2-hydroxypropanoic acid (CAS 959581-18-1), molecular formula C26H25NO7 and molecular weight 463.48 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (2S,3S)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-(3,5-dimethoxyphenyl)-2-hydroxypropanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 463.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
