Chemical Structure

Emtricitabine Enantiomer S-oxide(S-Isomer) CAS CATO-C4X-123232 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Emtricitabine Enantiomer S-oxide(S-Isomer).

CATO supplies Emtricitabine Enantiomer S-oxide(S-Isomer) (CAS CATO-C4X-123232), a certified reference material (molecular formula C8H10FN3O4S, MW 263.25 g/mol) for analytical method development and quality control.

The molecular framework of Emtricitabine Enantiomer S-oxide(S-Isomer) (C8H10FN3O4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
