Chemical Structure
Description
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.
D-Alanine Sofosbuvir (CAS 1064684-71-4), molecular formula C22H29FN3O9P and molecular weight 529.45 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, fluorine substitution, D-Alanine Sofosbuvir is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 529.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
