Chemical Structure
Description
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.
(S)-tert-butyl 2-((tert-butoxycarbonyl)amino)-5-oxohexanoate (CAS 945859-84-7) is a high-purity analytical reference standard with the molecular formula C15H27NO5 and a molecular weight of 301.38 g/mol.
The molecular framework of (S)-tert-butyl 2-((tert-butoxycarbonyl)amino)-5-oxohexanoate (C15H27NO5) is characterized by an amide group, a carboxylic acid 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
