Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 396.44 g/mol gives Fmoc-(N-gamma-ethyl)-L-glutamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Fmoc-(N-gamma-ethyl)-L-glutamine (CAS 676230-14-1), a certified reference material (molecular formula C22H24N2O5, MW 396.44 g/mol) for analytical method development and quality control.
The molecular framework of Fmoc-(N-gamma-ethyl)-L-glutamine (C22H24N2O5) is characterized by a flavonoid core, an amide 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Fmoc-(N-gamma-ethyl)-L-glutamine 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.
