Description

104884-43-7 T 506 5'-Uridylic acid, 2'-deoxy-5-fluoro-, mono(2-(trimethylammonio)ethyl) ester, hydroxide, inner salt, 3'-(9-octadecenoate), (Z)- T-506 5-Fluoro-2'-deoxy-3'-O-oleoyluridine-5'-(2-trimethylammoninoethyl)phosphate Mono(2-(trimethylammonio)ethyl) 2'-deoxy-5-fluoro-5'-uridylate hydroxide, inner salt, 3'-(9-octadecenoate), (Z)- (CAS 104884-43-7), molecular formula C32H55FN3O9P and molecular weight 675.77 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 104884-43-7 T 506 5'-Uridylic acid, 2'-deoxy-5-fluoro-, mono(2-(trimethylammonio)ethyl) ester, hydroxide, inner salt, 3'-(9-octadecenoate), (Z)- T-506 5-Fluoro-2'-deoxy-3'-O-oleoyluridine-5'-(2-trimethylammoninoethyl)phosphate Mono(2-(trimethylammonio)ethyl) 2'-deoxy-5-fluoro-5'-uridylate hydroxide, inner salt, 3'-(9-octadecenoate), (Z)- (C32H55FN3O9P) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
