Chemical Structure
Description
The occurrence of 2′-Deoxyuridine-2-13C;1,3-15N2 is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2′-Deoxyuridine-2-13C;1,3-15N2 (CAS 369656-76-8), a certified reference material (molecular formula C8[13C]H12[15N]2O5, MW 231.18 g/mol) for analytical method development and quality control.
Structurally, 2′-Deoxyuridine-2-13C;1,3-15N2 (C8[13C]H12[15N]2O5) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 231.18 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
