Sofosbuvir Impurity 96 CAS 1392015-05-2

Description

The occurrence of Sofosbuvir Impurity 96 is closely related to a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Sofosbuvir Impurity 96 (CAS 1392015-05-2), a pharmacopoeial impurity reference standard (molecular formula C17H15F5NO5P, MW 439.27 g/mol) used for the identification and quantification of trace impurities in APIs.

Sofosbuvir Impurity 96 (C17H15F5NO5P) contains a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

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.
