Chemical Structure
Description
Structurally, Tenofovir Alafenamide-d5 (Diastereomers) (C21H24D5N6O5P) contains deuterium isotope labeling, a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 481.50 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.
Tenofovir Alafenamide-d5 (Diastereomers) (CAS CATO-C4X-179738) is a high-purity analytical reference standard with the molecular formula C21H24D5N6O5P and a molecular weight of 481.50 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.
