Compared with other compounds in its class, the molecular weight of 335.38 g/mol gives S-Ethylglutathione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
S-Ethylglutathione (CAS 24425-52-3), molecular formula C12H21N3O6S and molecular weight 335.38 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of S-Ethylglutathione (C12H21N3O6S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
