Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 247.25 g/mol gives Emtricitabine Enantiomer distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Emtricitabine Enantiomer (CAS 137530-41-7) is a high-purity analytical reference standard with the molecular formula C8H10FN3O3S and a molecular weight of 247.25 g/mol.
Based on its molecular formula C8H10FN3O3S, Emtricitabine Enantiomer contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 247.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
