Chemical Structure
Description
The molecular framework of Ethyl (S)-2-(((S)-1-(benzyloxy)-1-oxopropan-2-yl)amino)pentanoate (C17H25NO4) is characterized by a steroid 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).
Ethyl (S)-2-(((S)-1-(benzyloxy)-1-oxopropan-2-yl)amino)pentanoate (CAS 112243-70-6), molecular formula C17H25NO4 and molecular weight 307.38 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
