Chemical Structure

5-Fluorouridine-5’-O-β-D-galactopyranoside CAS 149965-92-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 424.33 g/mol gives 5-Fluorouridine-5’-O-β-D-galactopyranoside distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Fluorouridine-5’-O-β-D-galactopyranoside (CAS 149965-92-4), molecular formula C15H21FN2O11 and molecular weight 424.33 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Fluorouridine-5’-O-β-D-galactopyranoside (C15H21FN2O11) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
