Description

2922-56-7 OOW3025SR1 S-Methyl glutathione Glycine, N-(N-L-gamma-glutamyl-S-methyl-L-cysteinyl)- Glycine, L-gamma-glutamyl-S-methyl-L-cysteinyl- Glutathione ester Glutathione S-methyl ester S-Methylglutathione L-gamma-Glutamyl-S-methyl-L-cysteinylglycine UNII-OOW3025SR1 (CAS 2922-56-7) is a high-purity analytical reference standard with the molecular formula C11H19N3O6S and a molecular weight of 321.35 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2922-56-7 OOW3025SR1 S-Methyl glutathione Glycine, N-(N-L-gamma-glutamyl-S-methyl-L-cysteinyl)- Glycine, L-gamma-glutamyl-S-methyl-L-cysteinyl- Glutathione ester Glutathione S-methyl ester S-Methylglutathione L-gamma-Glutamyl-S-methyl-L-cysteinylglycine UNII-OOW3025SR1 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 321.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 2922-56-7 OOW3025SR1 S-Methyl glutathione Glycine, N-(N-L-gamma-glutamyl-S-methyl-L-cysteinyl)- Glycine, L-gamma-glutamyl-S-methyl-L-cysteinyl- Glutathione ester Glutathione S-methyl ester S-Methylglutathione L-gamma-Glutamyl-S-methyl-L-cysteinylglycine UNII-OOW3025SR1 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.
