Chemical Structure
Description
The molecular framework of 5-Fluorouridine 5'-Triphosphate (C9H14FN2O15P3) is characterized by a carbohydrate-derived structure, an amide group, a phosphate ester group, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
5-Fluorouridine 5'-Triphosphate (CAS 3828-96-4) is a high-purity analytical reference standard with the molecular formula C9H14FN2O15P3 and a molecular weight of 502.13 g/mol.
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.
