(S)-(9H-Fluoren-9-yl)methyl 4-(tert-butoxymethyl)-2,5-dioxooxazolidine-3-carboxylate CAS 129288-44-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-(9H-Fluoren-9-yl)methyl 4-(tert-butoxymethyl)-2,5-dioxooxazolidine-3-carboxylate.

(S)-(9H-Fluoren-9-yl)methyl 4-(tert-butoxymethyl)-2,5-dioxooxazolidine-3-carboxylate (CAS 129288-44-4), molecular formula C23H23NO6 and molecular weight 409.43 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (S)-(9H-Fluoren-9-yl)methyl 4-(tert-butoxymethyl)-2,5-dioxooxazolidine-3-carboxylate (C23H23NO6) contains a flavonoid core, 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 409.43 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.
