Chemical Structure
Description
The occurrence of 4-C-Azido-2-deoxy-2-fluoro-β-D-arabinouridine is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-C-Azido-2-deoxy-2-fluoro-β-D-arabinouridine (CAS 173379-73-2), molecular formula C9H10FN5O5 and molecular weight 287.20 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-C-Azido-2-deoxy-2-fluoro-β-D-arabinouridine (C9H10FN5O5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 287.20 g/mol, it falls into the medium-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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
