Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Sodium (S)-5-amino-5-oxo-2-(2-phenylacetamido)pentanoate (CAS 104771-87-1) is a high-purity analytical reference standard with the molecular formula C13H15N2O4Na and a molecular weight of 286.26 g/mol.
The molecular framework of Sodium (S)-5-amino-5-oxo-2-(2-phenylacetamido)pentanoate (C13H15N2O4Na) is characterized by a nitrogen-containing heterocyclic scaffold, 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).
As a certified reference material (CRM), Sodium (S)-5-amino-5-oxo-2-(2-phenylacetamido)pentanoate 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.
