(3S,6S)-3-((tert-Butoxycarbonyl)amino)-4-oxo-1,2,3,4,6,7-hexahydroazepino[3,2,1-hi]indole-6-carboxylic acid (CAS 250682-47-4) is a high-purity analytical reference standard with the molecular formula C18H22N2O5 and a molecular weight of 346.38 g/mol.
The molecular framework of (3S,6S)-3-((tert-Butoxycarbonyl)amino)-4-oxo-1,2,3,4,6,7-hexahydroazepino[3,2,1-hi]indole-6-carboxylic acid (C18H22N2O5) 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.
