Chemical Structure
Description
The occurrence of 5-Bromo-2',3',5'-tri-O-acetyluridine is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Bromo-2',3',5'-tri-O-acetyluridine (CAS 105659-32-3), molecular formula C15H17BrN2O9 and molecular weight 449.21 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-Bromo-2',3',5'-tri-O-acetyluridine (C15H17BrN2O9) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 449.21 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
