(9H-fluoren-9-yl)methyl (S)-4-benzyl-5-oxooxazolidine-3-carboxylate (CAS 84000-03-3) is a high-purity analytical reference standard with the molecular formula C25H21NO4 and a molecular weight of 399.44 g/mol.

Structurally, (9H-fluoren-9-yl)methyl (S)-4-benzyl-5-oxooxazolidine-3-carboxylate (C25H21NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 399.44 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).

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.
