Chemical Structure

Sofosbuvir Impurity 16 CAS CATO-C4X-105216 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 260.22 g/mol gives Sofosbuvir Impurity 16 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Sofosbuvir Impurity 16 (CAS CATO-C4X-105216) is a certified pharmaceutical impurity reference standard with the molecular formula C10H13FN2O5 and a molecular weight of 260.22 g/mol.

Structurally, Sofosbuvir Impurity 16 (C10H13FN2O5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 260.22 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), Sofosbuvir Impurity 16 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
