Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 349.36 g/mol gives S-Acetyl-L-glutathione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
S-Acetyl-L-glutathione (CAS 3054-47-5), molecular formula C12H19N3O7S and molecular weight 349.36 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of S-Acetyl-L-glutathione (C12H19N3O7S) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), S-Acetyl-L-glutathione 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.
